Is Trevor crazy or just suffering from mental disorders in GTA 5? Read on to find out.

Why Is Trevor Crazy in GTA 5?

If while playing through GTA 5’s Story Mode, you think to yourself, “Trevor is crazy,” you’re not alone. Trevor is considered one of the most controversial characters in gaming, likely because of his dangerous mental disposition.

But why is Trevor crazy in GTA 5? Let’s delve deep into Trevor Philip’s crazy behavior in this article.

Why is Trevor Crazy in GTA 5?

Trevor suffers from several mental disorders: Borderline Personality Disorder, Antisocial Personality Disorder, and Intermittent Explosive Disorder. The combination of these three conditions creates the deadly and unpredictable concoction of Trevor Philips.

Trevor starts going crazy on a random guy.

The GTA 5 protagonist suffered physical and emotional abuse when he was young. Trevor’s father would physically abuse him, while his mom would also subject him to emotional stress. Trevor would carry the effects of his parents’ abuse well into adulthood. All the childhood trauma he suffered as a child explains Trevor’s extreme behavior as an adult.

Trevor’s Crazy Deeds in GTA 5

As you play through Trevor’s part in Story Mode, you will immediately realize how crazy Trevor is. Trevor makes unthinkable decisions throughout GTA 5, often taking things too far.

Trevor first displays deranged behavior when he kills The Lost MC’s leader, Johnny Klebitz, in Mr. Philips. When Johnny confronts Trevor for having an affair with his girlfriend, Trevor kills Johnny and blames Johnny for his death.

Trevor didn’t stop at killing The Lost MC leader. The deranged protagonist would eventually kill every member of The Lost MC in Blaine County, going as far as to ambush them at their base of operations to take over their arms business.

Philips will go on to eliminate all his business competition in Sandy Shores and do it using the most extreme methods he can think of. In the Main Story Mission Crystal Maze, for example, you will see Trevor ambush the O’Neil Brothers’ meth lab, kill everyone inside, and blow up the house completely.

What mental illness does Trevor have in GTA 5?

Trevor’s behavior meets the criteria for the following mental disorders:

  • Borderline Personality Disorder (BPD)
  • Antisocial Personality Disorder
  • Intermittent Explosive Disorder

Trevor likely suffers from Borderline Personality Disorder, among many other mental illnesses. A person with BPD will have difficulty controlling their emotions, which Trevor consistently displays throughout GTA 5.

Antisocial Personality Disorder is another mental illness that Trevor is very likely suffering from. A blatant disregard for laws, social norms, and other people’s rights characterizes Antisocial Personality Disorder. As you play GTA 5, you will see Trevor go against authority and disregard other people’s rights and opinions. This is portrayed in how Trevor treats Wade’s cousin Floyd, for example.

That said, no other mental illness fits Trevor Philips more than Intermittent Explosive Disorder or the inability to control impulses, especially those charged with anger. People with Intermittent Explosive Disorder display hostile and impulsive behavior and regularly go into rage-fueled outbursts even without provocation.

Is Trevor psychotic?

You are considered psychotic when you can no longer control your mind. As a result, someone with psychotic behavior will be unable to feel for others.

Trevor is a completely different animal. He isn’t psychotic by the definition of the word since he has no problems displaying emotion in the form of anger. Instead, Trevor falls neatly into another mental condition called Intermittent Explosive Disorder.

People with Intermittent Explosive Disorder will display frequent impulsive anger outbursts or aggression – something that occurs with Trevor very frequently throughout GTA 5. The condition is evident in the Rampage Missions, where Trevor goes on a rage trip without much thought about things he might destroy and people he might hurt.

Trevor’s Crazy Tendencies

A slew of mental illnesses plague GTA 5’s most controversial protagonist, Trevor. BPD, APD, and IED are some of the conditions that Trevor fits into, which causes him to become a rage-filled, unpredictable character who will go the extra mile to exact just a bit more pain on his enemies.

Trevor might be the craziest and most unpredictable man in GTA 5, but that doesn’t mean he’s a good-for-nothing character who only thinks about himself. Trevor is arguably the most loyal of the trio and will stick his head out for his team, even when they’re not named Franklin or Michael. He just gets a little crazy now and then.
