Like you see someone, maybe you recognize them and you don't like them, or they're just a stranger but they're alone and you feel angry. Would you ever actually attack somebody in real life?
It just seems like such a huge leap from wanting to hurt someone in theory and actually doing it. I can't imagine actually randomly attacking someone else. I've had intrusive thoughts and the occasional power fantasy, but it's just that. Fantasy. To think of it in a real, literal context feels cold and sick. I don't even want to do it for real. It can just be cathartic to entertain fictional scenarios sometimes.
