I think crazy and morally grey characters are hotter to me because they have something I don't. Kinda like how such characters sometimes "adopt" the resident goody two shoes character, in a sorta tsundere tough love way. I'm not coarse or moody around others. I kind of am by myself. I could not bring myself to be that way around others, but I don't think they're bad traits to have. Now, by that logic, I should also be into very sociable characters. And I am, but only certain kinds. For that matter, I'm not into all coarse characters. Some of them piss me off. But I also think more often than not it's a yay from me.
