I believe the personality disorder, antisocial personality disorder, is strongly, genuinely, and cinematically disturbingly depicted in the character The Joker, the main antagonist of The Dark Knight. In my analysis, I believe that he meets roughly most of seven of the diagnostic criteria in the DSM for Antisocial Personality Disorder (ASPD). A rough summary of the disorder, namely, the definition of what it says in the DSM, is that it’s “a pattern of disregard for and violation of the rights of others, criminality, impulsivity, and a failure to learn from experience.” He showed this from start to finish: cunningly using people, mass murder, and what I found most disturbing was his desire to see the moral decay of well-known, renowned figures, which he did with Harvey Dent. And it was successful. He plotted, schemed, and played on people’s emotions and feelings, using their very feelings against them to turn them toward lawlessness.

For the diagnostic criteria in the DSM, F60.2, Criterion A is a pervasive pattern of disregard for and violation of the rights of others, occurring since age 15, as indicated by three or more of the following. There is no real backstory with the Joker. He is actually vague about it, which makes him even harder to understand — why he became this way. So, in the movie, technically, if this was a real person, there would have to be more background, but this movie simply doesn’t have it. Even the stories he tells about how he got the scars on his face are contradictory lies, told in different ways concerning his personality.

Sometimes he appears manic, when displaying rage and sadness and then laughing, with rapid shifts between emotions. Later in this research, I would even wonder if he could have comorbidity with bipolar disorder, but this is a vague observation.

Criterion 1 — Failure to Conform to Social Norms

Criterion 1 says failure to conform to social norms with respect to lawful behaviors, as indicated by repeatedly performing acts that are grounds for arrest. This was present from start to finish. In the opening scene, there is a bank heist. The Joker is amongst them, but he remains obscure. He is the main boss of the operation, but he is actually participating in the heist. They all have masks on. They don’t know that he is with them. He has lied to every one of them.

This is the first act of lawlessness: theft. Then there is planned, calculated murder. What’s even more cunning is how he ordered every individual robber to kill the partner they were working with for the heist, essentially putting the blood in their hands.

More of his crimes include assault by various different people, and he also asks others and manipulates them to do so, which involves criminal solicitation and aiding and abetting, or accomplice liability. His crimes were obvious examples of criminal solicitation, where he commanded or even persuaded someone to commit a crime. In his case, it would be robbery and murder, which he did repeatedly throughout the movie.

He had a criminal’s mindset, with the added psychology of a deeply disturbed, apathetic man who initiated these crimes through others by the means of even his laughter at times and sheer enjoyment, sometimes with no clear motive other than the fact that it would lead to chaos. Obviously, these were many acts that were grounds for arrest. In the criterion where it says failure to conform to social norms with respect to lawful behaviors, it is laughable if anyone could even have a sense that he was trying to conform to any social norms.

Just like whenever he told Batman, “You’re a freak, just like me,” there might even be a possible link to schizotypal personality disorder, with his seemingly irrational philosophy, in a form of moral relativism/anti-civilizational cynicism, and beliefs about humanity and morality. Just about everybody who was around him was made uncomfortable, even those who worked with him. He was continuously noted for this.

Once again, even in a comedic way, there is a scene where he is talking to the mob of Gotham. They’re having a meeting, and the Joker is essentially rage-baiting them throughout the meeting. One of the mob members says, “Enough of the clown,” yelling at him, and the other members have to stop him. With how destructive and debased his behavior is, it’s laughable, disturbing, and cunning. In a sense, he is different from anybody else in the movie.

I would wonder if he wanted to corrupt someone so badly with his deceit because he wanted to make someone like him, possibly. There’s no real basis for this, just a side thought. I also wonder if this could have been birthed out of pride in himself for having this indifference. That’s what makes this character so unique to watch, because he is chaotic. He has just enough regard for himself to continue these acts and crimes, but he also puts himself in harm’s way.

In a scene, Batman is driving toward him, and he tells him, “Hit me, hit me,” over and over again, practically baiting him to do it. The Joker had no intention of moving, but Batman swerved off at the last minute and didn’t hit him. The Joker laughs afterward. There is a mind of instability, disregard for life, and disregard for oneself, but also just enough self-preservation to continue. There’s probably a thrill in the sense of it, playing with death itself.

On Dopamine and the Psychology of Chaos

There are a lot of misconceptions about dopamine — that it is simply the “pleasure chemical.” A couple of notable sources are Berridge and Robinson (2016), on the incentive-sensitization theory of addiction; Schultz (2016), on dopamine reward-prediction-error signaling; and Wise (2004), on dopamine, learning, and motivation. With various quotes and thoughts I read from this point of view, I would argue that there was a constant risk-reward system with the Joker. When you’re operating on a level that no criminal in Gotham is doing currently, if I put myself in his mind, there would be an ecstasy and a high associated with that — the loop of anticipation and the drive, getting the payoff in the end when you make the right choice, and then the fatigue after the events and schemes he would orchestrate.

I wonder if, after the heist and all the different things that he did throughout the movie, he sat alone, pondering and ruminating on it. There is a sense of madness, namely, pleasure in the madness. Self-destructive behavior that doesn’t actually come true, with him standing in front of the bike and it not hitting him. I would even argue further that even after it didn’t hit him, he started laughing and kicked one of his associates on the ground, acting like he had gotten shocked. Then he did these absurd movements and made these sounds. I wonder if he had a manic episode in that moment.

That prompted the question you had for this report, with the scenarios that I was running through my head of crime and sabotaging others. There was a sense of a rush, namely, that I would never act on such things, that I will mention later. But putting myself in this mindset and role of somebody who has this disorder, there is a thrill in planning it. And then, when the plan comes through, you don’t get caught. You are the mastermind, sometimes deliberately getting so close to the person, crime, or whatever you’re trying to do to sabotage, and you’re still not caught. I could see the excitement that a person with this disorder might feel.

So I would even argue further that the type of high and dopamine release that was going on in the Joker’s brain throughout the movie must have been unthinkable, to the point where an unstable mind would even want to do such things, given this possible disorder, or see the thrill in his sabotage of others. He had people at his mercy throughout the whole movie, even whenever he was interrogated. And he saw people not for what they do, but for who they are, and he sought to shatter that. And if he couldn’t shatter it, he would just use them as a pawn.

He has disregard for life. They were just a piece of flesh in his eyes. Whether they live or die, they serve their purpose. It could be laughable, or it could just be plain silence, not even giving the person much thought whenever they’re done being discarded. Just like in the beginning with the robbers — there’s no other mention of these robbers that he killed and indirectly killed through the persuasion of the others doing it. He was, in fact, I would say, a terror to Gotham. Walking ruin and destruction.

The type of destruction that’s not outwardly physical, but inwardly, slowly corrupting people with high moral standards, like Harvey Dent, just to show the world that this person could fall. All of humanity could fall. And there might have been a sense of grandiosity within him, that he was able to cause it, though I would not argue that he necessarily met enough schizophrenic criteria for that to be the case. People with grandiose delusions probably do not necessarily want to end life, but he put himself in harm’s way continuously. The scene with telling Batman to run him over is proof of that.

Criterion 2 — Deceitfulness

Number 2 of the DSM says, for the criteria, deceitfulness, as indicated by repeated lying, use of aliases, or conning others for personal profit or pleasure. Once again, continuously throughout the movie, which I’ve already explained. Forgive my disorderly thoughts — this is a deep character and deep research, trying to make sense of everything.

Concerning deceitfulness, I already mentioned this with the robbers in the bank heist, not revealing himself, having all of them killed in the end. Though it wasn’t directly him lying, through his chaos, he manipulated the situation. With how genius he is, Harvey Dent confessed to falsely being Batman, to help tame all of the chaos going on, thanks to the Joker’s deceitfulness and conmanship.

I believe the most shattering part of this movie is where you see the real depravity — this is how he sees people’s love. Harvey Dent was a man of integrity, a lawyer fighting for people’s cause and Gotham. But he noticed something. He doesn’t know that Batman is Bruce Wayne. Harvey Dent is with Rachel, one of Bruce Wayne’s former girlfriends, for whom he still has feelings. Throughout the movie, Bruce repeatedly tries to persuade her to get back with him, which doesn’t happen in the end — she chooses Harvey Dent.

This is eventually lied about by Alfred, in a letter that she wrote to Bruce before her death. Alfred rewrites the letter, saying that she chose Bruce, when in reality he burned the original letter. The original said that she chose Harvey Dent to have a future with, not Bruce — even though she encouraged him to stop being Batman.

In the interrogation room, getting back on the research topic, Harvey Dent and Rachel had been kidnapped, which the Joker planned and put together perfectly. They’re in two separate locations, with bombs at both locations where they’re being held. But the Joker notices, along with Batman, Bruce Wayne, in a prior scene, that Rachel is at this party, and the Joker shows up.

He’s aware that Harvey and Rachel have a thing, even though it is obscure throughout the movie, since they work together and try to be professional, but the Joker notices this. Batman shows up to try to capture the Joker and his associates, crashing the party because they were looking for Harvey Dent.

The Joker grabs Rachel, hanging her out of a window. Batman says, “Let her go.” The Joker says, “Very poor choice of words,” and he lets her go, sliding her off the building. They are many stories up. While he does this, he is also laughing. Once again, I wonder if this is just manic behavior at the chaos, and once again, the apathy for life and human suffering that he’s causing.

Batman saves her. But the Joker had such analytical skills that he noticed the distress Batman was in to rescue her. Astonishingly, he put it together in his mind that, even though he didn’t know he was Bruce Wayne, clearly he had a thing for Rachel, Harvey Dent’s girlfriend.

Now, in the interrogation room, he has Batman. Whenever he reveals Rachel’s being held as well, Batman gets angry, throws him against the wall, starts assaulting him, saying over and over, yelling, “Where are they?” The Joker has an underlying insinuation — he is talking about how Batman has a thing for Harvey Dent’s girlfriend. This makes him even angrier, and this confirms even further, for the Joker, that it is true.

So whenever he’s about to give the addresses, he also tells him, “You’re at my mercy.” Even further, I’d wonder if this is reaffirming the rush that comes from having everyone at his mercy in that moment. Batman, being the key figure who could stop all of this, is in his hands at that moment.

When given the addresses to Harvey Dent and Rachel, where they’re being kept with the explosives that are timed, only one of them could be saved. He switches the addresses, lies to Batman, and says that he gives him the address of Harvey Dent, not Rachel.

Also, to be noted, one of the characters I did not mention — the police commissioner throughout the movie, Gordon — believes he is going to Harvey. Batman believes he’s going to Rachel. It’s switched. It’s a paradox in everybody else’s mind, because of the chaos and sheer absurdity of what’s going on, but in the Joker’s mind, it’s all planned, calculated, and perfect. Everyone is at his mercy. It could be almost a godlike experience — that he’s in control. Almost like everyone is his created beings, not that he made them, but that he created the present person, in distress, that they now are, caused by his actions.

Batman arrives. He gets to Harvey, rescues him. And what cuts even deeper is the fact that Harvey is on the phone with Rachel. He’s screaming, “Rachel,” over and over again, telling Batman, “Why did you come for me?” She’s talking to him, trying to comfort him, saying it’s going to be okay. And then, as she continues, it’s cut off, and the explosion goes off, killing her instantly.

The explosion at Harvey Dent’s location occurs as well. Gasoline had previously been spilled on Harvey’s face, and from the explosion, half of his face gets caught on fire, getting disfigured. And that births the new name Two-Face. This starts the moral decay of Harvey, who was Gotham’s White Knight. Now he is going to fall into moral decay.

The Joker got multiple people from this, all out of deceitfulness. Rachel died. Harvey dies psychologically. Batman survives, but he carries the guilt of Rachel and mourns the loss of her. Gotham loses its White Knight, Harvey Dent.

It’s astonishingly calculated and accurate — this use of conning, lying, and deceitfulness — and the diagnostic criteria. Two criteria have already been met.

Criterion 3 — Impulsivity

Number 3 in the criteria is impulsivity or failure to plan ahead. He’s a confusing villain and a psychological study, because he planned ahead constantly, but he also did things impulsively. There were even dangers to his life. An example was stepping in front of Batman on the bike. In fact, he was in danger throughout the whole movie. Once his character and identity are revealed, he has a face for who he is. Throughout this movie, he is wearing makeup, and he has scars on his face as well, which could be expounded on later concerning this diagnosis.

During the interrogation, it was emotionally provocative, except, almost ironically, where you could even laugh in a sense — it was everybody but him. He’s relaxed sitting there, as if nothing is going on, but it’s because everything is going according to plan. He’s inconsistent. But I would argue that he doesn’t meet this criterion, because the impulsivity shown is more so in the moment of something he planned ahead, but not enough to establish the criterion.

Criterion 4 — Irritability and Aggressiveness

I would argue Criterion 4 says irritability and aggressiveness, as indicated by repeated physical fights or assaults. He assaulted various people, murdered various people, planned for it, and manipulated others to do it. It was peak moral compromise, not even decay — he was already decayed enough to begin with. It’s just that this disorder was amplifying it.

And one could even ponder, with critical thinking and hypothesis: Was this something that accumulated over time for this to become a disorder? Was it trauma? Something he saw? That’s the ambiguity and obscurity of it, because there is no backstory. He just shows up on the scene. And, like Alfred, Batman’s butler, telling a story of somebody else, he says, “Some men just want to watch the world burn.” The Joker has no real motive. It’s just chaos.

Criterion 4 is obvious.

Criterion 5 — Reckless Disregard for Safety

Criterion 5 says reckless disregard for safety of self or others. Things are already mentioned, but this was repeated: the bank robbery, arranging for his own men to kill each other, the final survivor he kills, the public attacks, and the murder and killing of innocent people, creating panic. He showed little concern for civilian safety. In fact, in his eyes, nobody was really a civilian — they’re all the objects of his goals of wreckage on Gotham.

At the fundraiser, he endangered everybody at Bruce Wayne’s party while he was searching for Harvey Dent. This comes to the part where he has disregard for his own safety, that we mentioned. He stands in the road, wanting Batman to hit him, in a sense rage-baiting him — complete disregard for his own life.

This is after the creation of Two-Face, but this is the complete nail in the coffin for this criterion. With Harvey Dent becoming Two-Face, now one of the other antagonists that he created, Harvey Dent would do a coin flip, heads or tails, based on a decision.

The Joker goes to see him in the hospital, which actually later gets blown up, though not by the Joker. He puts a gun in Harvey Dent’s hand, and then puts the gun to his own head, telling Harvey to kill him. Harvey flips the coin, and the Joker lives. He was willing to die if it helped prove his point that the perceived, highly esteemed moral figure, Harvey Dent, could even fall for something like murder.

He also had explosives planted on two boats, full of civilians and prisoners. Hundreds of people could have died in this, though none did — one of his failed plans, which was very few. He doesn’t have any concern for human safety or his own life. He could live or die either way, because he got the ball rolling, and the domino effect continued on.

His corruption spread to everybody, even those he never met. Alfred, Bruce Wayne’s butler, receives the letter from Rachel, basically saying that she turned Bruce down and chose Harvey. But thinking about Bruce’s mental health after the death of Rachel, he burned that letter and made a new one, crafting his own, saying that she did choose Bruce.

Obviously, this letter could have been sustainable if she was living, but now she’s dead. Alfred had to go to those measures to do such a thing, which later, in The Dark Knight Rises, gets brought up, and Alfred confesses what he did. It ruined Alfred and Bruce’s relationship, because Alfred wanted to do anything possible to get him to stop being Batman. And they part ways, until the end, when they are reconciled.

The cause and effect of what the Joker did bled into the next movie, and continued on.

Criterion 6 — Consistent Irresponsibility

Number 6, consistent irresponsibility, as indicated by repeated failure to sustain consistent work behavior or honor financial obligations. This is a weak criterion for the Joker. He doesn’t have financial obligations. His only obligations and goals are chaos and the wreckage of other people’s lives. I would say he does not meet this criterion.

Criterion 7 — Lack of Remorse

Number 7, lack of remorse, as indicated by being indifferent to or rationalizing having hurt, mistreated, or stolen from another. Things that have already been mentioned — the manipulation of Harvey Dent leading to his moral decay. There was no remorse ever. He doesn’t express guilt, but he rationalizes his actions with his beliefs that people are just selfish and social order is meaningless.

His philosophy is basically asking: Are people moral genuinely, or are they only moral because their lives are comfortable and their circumstances allow them to be? With him later, in the interrogation, saying, “These people will eat each other.”

On a side note, a part of me could even agree with this, in a sense. There was a warning of a snowstorm coming when I worked at Sprouts Farmers Market a year ago, and people flooded the store buying inhumane amounts of groceries. Eggs were empty. All sorts of food — over $700 worth of groceries. The entire store was backed up, and shelves were empty.

In a sense, the people were eating each other, because the only thoughts they had were of themselves and helping their families. In the name of morality — but really, it is immoral, because they are neglecting the needs of others who need food as well, where they could have simply gotten what they needed and kept going. It turns out the snowstorm wasn’t even as severe as what they said. I was angry that day.

The literal quote he says: “When the chips are down, these civilized people, they’ll eat each other.” His argument is that people aren’t evil all the time. It goes deeper. The belief is that civilization suppresses what people really are. The social constructs, laws, and moralities placed around people are the things holding them back from embracing what they really want to do, namely, what is wrong.

My genuine belief is that there is good and evil, black and white, and there’s nothing further beyond that. But the Joker takes this to a more twisted level in his philosophy. Namely, not that his analysis is twisted, but because of his actions and what he’s doing. The pressure reveals the person’s real self.

He also goes further. You could say his logic is, arguably — though he doesn’t mention it — that Batman, one of whose rules is not to kill, becomes conflicted, because if he doesn’t kill the Joker, how many more innocent lives will die? It could be him proving a point that Batman’s principles are conditional. What if Batman were to kill him on the spot, especially because of Rachel? From his perspective, morality was temporary.

The Joker seeks to press people’s consciences as deeply as he can.

Another thing he says is very interesting — his own quote from the movie: “I’m not a monster. I’m just ahead of the curve.” Practically, this is a justification for his actions and his mind. He’s not even taking responsibility for his actions, but actually justifying his logic and seeing it actively happen in front of him throughout the movie.

He sees himself as different and ahead of the curve compared to others. He’s more honest, he believes. He’s possibly thinking other people have the same darkness and the capacity for great violence and evil that he’s demonstrating throughout all of this movie. The only difference is that people are held back by social norms — the things keeping them bound.

The terminology “pressure breaks pipes” has an underlying truth to it, not needing a hypothesis, but in simple human observation: a long day at work, getting angry at the person cutting you off, the incident of the snowstorm showing people’s greed and disregard for life.

I’ve even had the thought — what if a famine were to hit America? Then you would really see how far people’s morality, and, us being in the Bible Belt, especially professed religion, would take them in those moments. Do these standards stand the test in that? It’s not even necessarily an evil philosophy. It’s just the fact that it’s not only chaos — it shows people what they are. It’s pressure. It’s when you put someone on the spot, when you’re out of options.

In a sense, he’s unleashing what he believes to be true humanity, and in his eyes, he is not an exception. He’s humanity without the comforting moral illusions. In a sense, he’s a case study of what’s underneath all of us — in a sense, someone who is reprobate.

reprobate /ˈreprəˌbāt/ — “morally corrupt: DEPRAVED” (Merriam-Webster)

Dissociation and the Void

I could have a hypothesis where the Joker dealt with dissociation, where all of this didn’t even seem real. Detached. He’s watching the entire world burn — a story that he created that doesn’t have a good end here. That leads to Batman taking the fall for Harvey Dent’s death, because if people were to discover his moral decay and the murders he committed, Gotham would lose hope. So the Dark Knight takes the fall in place of the White Knight.

Batman had to become deceitful on behalf of the Joker, even though, in the end, he was captured. In a sense, there’s a dreamlike sensation to it.

Morality. Humanity. Do we do good? Do we do good for the sake of ourselves or for the sake of others? Do we love our neighbor as we love ourselves? Or do we just want to love ourselves? Are we obligated to love our neighbor, whom we don’t want to love in the first place, but we just want our conscience appeased that we’re doing the right thing in the moment? And the pride in it — maybe even the praise in it.

Possibly, even the Joker had these thoughts, reaffirming that his philosophy was becoming true — not true as in it is correct, but true from the circumstances he created.

If there very much does become a famine or war in America, which I have no hope of happening, I do know this: though men try to hide behind philosophy, whatever belief and morality they have, their capacity for love and compassion will be revealed.

What they call obligation for family will become greed and covetousness. They will disregard others’ lives to feed the mouths of their children, but not share a morsel with a stranger or another family in need. You’ll see if men only think about themselves, or if they think about others.

The collapse of a nation is not the collapse of morality. The collapse of the nation shows that the morality was already ready to burst at any moment. It was just these social norms — everything in order, what’s good, not starving, waking up every day with every imaginable thing in our eyes. We can look up anything on the internet, go to whatever we want in the world. It’s like a dream, and it will become people’s nightmare if anything befalls this nation.

I’ve even almost ruminated with nihilistic delusions that something will befall this world, or America — not the end of humanity, but the end of man’s morality, which was built on sand in the first place.

Though I’ve never justified anything the Joker did, it’s disturbing. But to put my mind on someone with this disorder, I would argue the comorbidity of this and schizophrenia. Consider someone even grandiose or persecutory, thinking everybody is against them, that someone is out to get them, or that they’re going to be the next leader or prophet, to show themselves what humanity really is.

I wonder if he saw himself like that. No — I would push this further, that he possibly did. Whenever he said, “I’m ahead of the curve,” showing his lifted-up heart about himself, justifying murder, death, decay, manipulation, and just about every single crime he committed up until this point of the interrogation.

Nietzsche stated, “If you gaze long into the abyss, the abyss also gazes into you.” But my version, what I more so prefer, is: if you stare into the void, it stares back — or, just staring into the void itself.

The void being nothing. Empty, invalid, just space — not necessarily space, but the darkness of humanity, where someone very well could become like the Joker, justifying their actions.

I would even argue further that Hitler is a prime example — his hatred for Jews, and anyone not with blonde hair and blue eyes, justification of genocide. Though this report is not about him, but merely just a note.

Diagnostic Summary

Concerning question number two, I believe I went over most of the different illnesses, and most of the symptoms of the illness, as far as explanation, with everything that has been talked about in the movie.

He met more than three of the criteria, which is enough for a diagnosis, if the necessary developmental and historical information were available, given the clear lawlessness and disregard for humanity.

What I found the most shocking is his justification, even for this nature of destruction, that he caused in all of the crime and awful things he did to people. I would say this is one of the closest realistic portrayals of this disorder, though it has no credibility, coming from someone with no credentials and no actual PhD, which I don’t have. I’m just a 28-year-old college freshman.

Causal Factors and Treatment

I believe causal factors were explained. There is no real nature and nurture in the character of the Joker. He disappears onto the scene. He gives a vague backstory of how he got the scars on his face, in different versions, emotionally, every single time, but all three of them are lies. Not even, in a sense, necessarily self-loathing, but just the madness behind him and sheer absurdity in the moment.

That’s what makes him an appealing character, because there’s not much backstory. He disappears and turns the whole city of Gotham upside down — not necessarily the city, but the hearts of men. In a sense, he created these beings of corruption.

There is no treatment for the Joker. I would argue that treating this man, there’s no hope. Though every clinician seeks that, and if I did become a therapist, I wouldn’t deny his case. But in the back of my head, I genuinely would think this man might be a lost cause — that he’s this far gone to commit these actions, that his conscience may very well not exist anymore, or that he could no longer tell right from wrong because he’s stuck in this delusional mentality.

Which, in a sense, could be correct about his philosophy of humanity under pressure, but the delusion that what he’s doing is justifiable is probably irreversible, even with treatment, in my opinion.

Concerning treatment, I chose cognitive behavioral therapy, basically helping change harmful patterns and actions, and how your actions affect other people — even in the attempt of harm. But with someone with the severity of the case of the Joker, I’m not sure there would be any breach of conscience or any benefit from therapy.

Besides this, and medication, these are the two things that I would say, in my opinion, are the best course of action: longevity and consistency with the client. Because, in a sense, helping that person retrain their thoughts of apathy towards others and daily habits, and showing the client that there’s someone who cares enough about them to keep meeting with them and addressing these things, could very much lead to cognitive and behavioral change, just in that alone.

Because it doesn’t need to be observed that when people see that someone cares for them, it strikes something in the heart. Though this could be argued, obviously, especially concerning trauma bonding — because the person is incapable of receiving genuine love in a relationship, and compassion, because they’re used to chaos: abusive, emotional, maybe even physical, behavior.

And with dopamine included, because the relationship is an uncertainty system built upon chaos, if they date someone who is stable and genuine, they will break up with them, because they cannot receive these things.

The Wider Impact on Gotham

This disorder had a vast impact on everyone inside the entire movie.

Concerning the general population, Gotham became psychologically terrified. Fear became a weapon. He threatened hospitals, public gatherings were attacked, and he put citizens in situations that were life-or-death decisions.

The mob lost control. The Joker starts off, and it seems like he’s helping the mob, and the mob is helping him accomplish his goals. He encourages killing Batman, but this was cunning — he actually helps destroy the stability of organized crime.

Later on in the movie, he burns the mob’s money just to show he’s not motivated by criminal attitudes. In a way, he says, “You have something you want to preserve. I don’t.” This also points even further to the diagnosis, because he’s showing his psychological power over people, since he has disregard for himself. He has nothing to lose, in a sense, and no real motive — just to cause havoc, whether he lives or dies.

Once the domino effect started, he had already won.

The police force was in shambles in Gotham. They had to protect the targets he identified. Officers were living in fear of possible ambushes. Hostages had to be rescued continuously. Public buildings and threats caused severe anxiety.

There was also a noted scene where there was a corrupted officer whom the Joker threatened through his family, and he persuaded him to help him in one of his operations. This led to Gordon, the police commissioner throughout the movie, having self-conflict over whom to trust.

He doesn’t attack individual police officers. It’s an attack on order. And when there’s no order, there’s chaos. And when there’s chaos, there’s even the possibility of anarchy.

One of the key figures of the psychological impact was Harvey Dent. Due to his actions, Harvey Dent was Gotham’s White Knight in their eyes. He was strong in the legal system. Instead of becoming Batman, how he fought organized crime was through the court and legal system. Gotham believed that goodness could win.

Instead of the Joker killing Harvey Dent, he ruins him. This goes with Rachel’s death — half of his face gets burned, he becomes Two-Face, and he also learns that Gordon’s police operation actually contributed to Rachel’s vulnerability and capture. This led to an extreme psychological collapse and hatred for everybody, especially his former allies.

And so he becomes Two-Face.

The Joker accomplished more than killing anybody. He took a symbol of justice and turned him into a weapon of revenge.

Rachel’s death is catastrophic as well. This devastated Harvey, Bruce Wayne, Jim Gordon, Alfred, and the people who loved her, obviously.

What’s even more tragic is Bruce Wayne imagining that, if Gotham became safe, he could have stopped being Batman and had a normal life with Rachel, because that was one of the conditions she set for them to be together. And whenever he persuaded her later on, with how things were going with Harvey Dent, he could stop being Batman. He wanted a future with her. That was destroyed through her death.

And not only that — with insult to injury, Alfred burning the note and crafting the one he made to protect his conscience, Bruce believed a lie that Alfred crafted for years, thinking that Rachel actually wanted to choose him, when Rachel actually chose Harvey Dent.

Batman became very desperate in his behavior, and, as usual, his methods of fighting crime became increasingly extreme. The Joker repeatedly pressured him to abandon the boundaries he had set, especially concerning killing.

The interrogation scene maps onto this perfectly. Bruce becomes so enraged with learning about Rachel and finding Harvey Dent that he starts to beat the Joker. He knew this was a moral compromise, because whenever he was in the police station interrogation room, he put a chair on the door, blocking it so they couldn’t get inside, and he starts beating on him.

Also, it’s more disturbing because the Joker is laughing while he’s getting beaten. There’s not even a sense of him saying to stop — he’s just laughing at all of it falling into place. He created the right circumstances for Batman to have a moral compromise in his ethics.

Harvey Dent attacks Gordon’s family out of vengeance on behalf of Rachel. He kidnaps his family. And since Gordon is fighting the Joker, his personal life has now entered his work life, all because of the Joker.

The Ferry Experiment

The Joker also had a mapped ferry experiment. He put two groups of people in Gotham against each other. Both of them have a detonator. On one boat, there are civilians; on the other, there are prisoners with guards. He has a genius hypothesis, which can be observed, though he didn’t actually say it — by his actions, you can tell it was a real thing.

When people are terrified enough, morality will collapse.

This is the one time that the Joker failed throughout the movie, and there was a glimmer of hope, because one of the prisoners takes the detonator and says, “I’m gonna do what I should have done a long time ago,” and he throws the detonator out of the window into the water.

This shatters some of his philosophy — and even mine, and my own twisted, nihilistic, darkened thinking, when I get embittered with the world, society, and even myself, being the object of my own hatred.

Fear doesn’t automatically destroy morality in people. There is good in mankind.

He created distrust amongst just about everybody. The police officers might be corrupted. The mob and the criminals could have betrayed each other, as could the people he used.

There was also a time when he cunningly kidnapped people, put them in Joker masks, and duct-taped guns to their arms, where it looked like they were pointing the guns and working for him, but they were regular civilians — creating even more distrust.

Also, with threats and the possibility that certain buildings might be targeted, he basically created social paranoia.

Overall, he created a domino effect: the Joker’s crimes, fear, police pressure, desperation, Batman’s escalation, and his personal life as Bruce Wayne infiltrating his crime-fighting life; Rachel’s death; Harvey’s psychological meltdown, then his transformation into Two-Face; more violence; and Gotham’s loss of faith.

In a sense, practically, he’s not just a murderer — he’s a psychological saboteur.

He operated on three different levels. Physically, he killed people, blew up a hospital, burned money, attacked the police and institutions, and created overall terror and danger. Psychologically, he produced fear, paranoia, pain, grief, desperation, rage, unforgiveness, and moral uncertainty. Morally, he was trying to convince people that morality is something that disappears whenever pressure is applied. But the ferry incident showed that this partly failed. It also showed that he succeeded in the case of Harvey Dent.

He wasn’t trying to be stronger than Batman. In a sense, he was saying, “Your principles are temporary.”

The entire movie is a pendulum, swinging left and right: is the Joker correct about Gotham and humanity, or can people overcome in spite of great affliction and pressure?

Two Hypothetical Case Illustrations

To illustrate what this kind of calculated psychological cruelty might look like in practice, consider a hypothetical case: someone with this disorder attending the funeral of a young man who had died by suicide, whose father was a deeply devout, older religious man. Prior to his son’s death, the son had repeatedly confided in his father about severe depression, and the father had responded with the language he knew — that his son needed deliverance, that he needed to believe harder, that his suffering was spiritual rather than psychological. The son eventually took his own life.

A person with this disorder, in this hypothetical, might exploit exactly the vulnerability that moment creates. They could take the stage to deliver a eulogy — genuinely skilled at moving a crowd, recalling real memories of the son with apparent warmth and sincerity. The manipulation would lie not in the content of the praise, which could be sincere, but in the timing and intent behind it: using the family’s grief as leverage, building emotional trust with the room, and then turning directly to the father to deliver a single devastating line — something to the effect of, “he’s dead because of you, and because of what you told him, you’ll never see him again.” Then walking off stage, having calculated the moment for maximum psychological damage.

The clinical significance of this hypothetical isn’t the cruelty alone — it’s the precision. This is not impulsive rage. It is patient, socially fluent, timed to a moment when the target is already at his most exposed, using grief itself as the delivery mechanism. It reflects the broader pattern already discussed: viewing another person’s private moral failure as something to be exploited for maximum psychological effect, rather than addressed directly, confronted honestly, or forgiven. It is retribution disguised as eulogy — using genuine eloquence and real affection for the deceased as the vehicle for calculated harm to the living.

Because I may very well one day, as a licensed therapist, if I can get there, sit with people with such darkness in their hearts. Sit in the darkness. Don’t become it. Be compassionate. Seek to heal, not grow cold.

A second hypothetical illustrates a longer-horizon version of the same pattern. Consider someone with this disorder who learns that a close acquaintance’s husband has been unfaithful, and that the wife is willing to work toward reconciliation. In this person’s internal framework, the husband’s infidelity disqualifies him from a second chance — regardless of the wife’s own wishes or the couple’s actual capacity to rebuild trust. Rather than intervening directly, or simply disengaging, the person constructs an elaborate, delayed mechanism to guarantee the marriage’s failure while appearing, at every step, supportive.

The scheme: hire an actor based overseas to pose as a marriage counselor, complete with fabricated credentials, reviews, and online sessions convincing enough that the couple has no reason to doubt him. Over six sessions — the number chosen deliberately, echoing the number associated with human fallibility — the fake counselor provides genuinely competent-sounding advice, appearing to help the couple make real progress. Then, using access to the husband’s phone, the person fabricates a text exchange between the husband and the “counselor,” implying a second affair and a request to keep it confidential under the guise of counselor-client privilege.

At what would have been session seven, instead of another appointment, the “counselor” contacts the wife directly, forwarding the fabricated messages and citing a fictional legal obligation to disclose infidelity under his country’s counseling regulations. The wife, receiving what looks like a horrifying and credible betrayal from a source she trusts, ends the marriage for good. The husband is left with no way to explain himself — the counseling service disappears, no sessions were recorded, the “counselor’s” identity was fabricated from the start, and pursuing legal recourse across international lines is functionally impossible.

What this illustrates clinically is patience over impulsivity — the willingness to invest months and real resources into a scheme with no immediate payoff, purely to guarantee a specific, permanent outcome for someone the person has already privately judged and sentenced. It is not rage acted out in the moment. It is rage translated into architecture — engineered, delayed, and cunningly, utterly deniable.

Closing Thoughts

I believe the movie depicted this perfectly. That can be vastly critiqued, but it’s just my opinion. There are deep psychological and cinematic portrayals in this that go beyond movie-making — into psychological depth, and the darkness of the mind and mental illness itself.
