Well, in my opinion, if you want to be like this, there's something wrong with you lol, but you're not a psychopath. It's not something you can just attain like studying hard and acing a math test, it's just something you are. And let me say, frankly, it's not cool and doesn't make you badass, and can cause complications in your life if you don't know how to keep yourself under control.

Everybody wants to be psycho but I guarantee if it came right down to it most of these tryhards would piss themselves when confronted by someone who actually was like that. Maybe you do fantasize about violence, but then again so do a lot of people. But frankly, in order for me to even consider taking you seriously you'd have to be fine with brutal torture and mass murder for the sheet sadism and hell of it, not because you have issues.

Stop trying to be something you aren't, it just reeks of desperation.
