That's my favorite kind of hot. It's probably linked to some sort of unhealthy thought process deep in my brain and it's a TERRIBLE impulse to listen to when picking romantic partners, but there's something arousing about a smoking hot guy who can also be monstrously terrifying/evil. It's really only appealing in fiction, I think, and not so much IRL, because IRL you have to deal with the consequences of fucking a psychopath...

Plus it's just fascinating to me how a human face can go from being so attractive to being so frightening. Some actors are really impressive to me just for how unappealing they can make their beautiful, perfect faces by contorting them with rage.
