I think I want to hurt someone before warning then.
Why do you think it's okay to hurt people?
It's not okay, I'm just being an asshole.
It's not okay to purposely harm people. Especially if you know that you're doing it because you're a jerk. You will not have many friends in life if you go through it like this.
It's fun to get away with it.
The people you are harming will fight back and if they have friends, will overwhelm you. The police will also get involved and arrest you. Find another way to take out your aggression.
