Question

If any of you know anything about psychology or psychiatry, this is the question for you.

I know a guy who watches people commit suicide because it's "hot." He will purposely look up videos of people taking their lives because he likes it. He's known as the stupid kid in class, even I think of him as stupid, and I don't really know what to think of him now. 

What would he be considered? A masochist is "a person who derives sexual gratification from their own pain or humiliation," a sadist is "a person who derives pleasure, especially sexual gratification, from inflicting pain or humiliation on others," a psychopath is "a person suffering from chronic mental disorder with abnormal or violent social behavior," and a sociopath is "a person with a personality disorder manifesting itself in extreme antisocial attitudes and behavior and a lack of conscience."

He doesn't inflict pain on others, he doesn't have violent social behavior, and he isn't exactly anti-social. 

This might seem weird to ask of other people on the internet, but I really don't know what to think of this. You can tell that my views on suicide are pretty biased and that I think people should understand it more, but I definitely can't understand this. 

It was just a question with a possibly unknown or impossible answer, but I hope you have a good day! Bye Bye!
