Hello, so I've been awfully curious and worried about this certain individual that I know very closely. He isn't really a harmful or rude individual, quite the opposite actually. He is known for being an introvert who is quite mild-mannered and polite in real life. He doesn't talk unless spoken to, so he overall is a very private person. How does this in anyway trigger this suspicion you may ask? Well how he thinks internally and acts in closed doors is different. What I state is based on what he has said to be and how he views things, if you were to examine it at surface value, I'd appreciate it.

Early Life:

He seems to struggle with being whether bored, irritated, or depressed. He constantly tells me life is boring and lacks any excitement. He used to be incredibly agressive and hostile in his later years in high school despite being bullied severely in elementary and having a rather chaotic household. Despite being incredibly intelligent, his teacher failed him because he lashed out at one of his teachers during class. 

He always told me he hates those around him and wished for their death. He has had traumatic moments that made him feel weak and vulnerable, and he despises it. He absolutely seems to hate and be disgusted by the idea of being empathetic towards others. That they all deserve to be used or killed in a way. He is not really machiavellian by any means, but he certainly has a very horrible mentality.

The emotions he explained he feels:

-Irritated (he feels that his life is directionless and wants control over it)

-Bored

-Depressed (he said he can cry about things, but he has to actually push it out, and it rarely ever happens genuinely)

-Minimal guilt when it comes to only those he values

-Angry/frustrated (he can let his temper out when he believes that others are attempting to control/hurt him, whether true or not.

He believes currently in his life that he has no direction to go really, and that since he is isolated from doing anything interesting or harmful towards others, he now lacks that admiration and sense of pride that his close group of friends would give him. Once again, he is mild-mannered, but nevertheless constantly having a chip on his shoulder.

The only time he has gotten in trouble with the law was when he dated an ex who dumped him and he decided to send death threats and actually attempted to plan to hurt/kill her until she told her family and he was investigated. Nothing happened to him from what he told me, but he simply felt like she was throwing him under the bus and that she didn't deserve to live.

I wish I could write more, but overall I'd prefer answering questions based on what I've seen about him and what he has told me. My question is if he exhibits traits that are anti-social in general? He doesn't seem to violate the rights of others often, if at all. But he is overall agressive and tries to be domineering when it really gets to him.
