In human relationships there's nothing more attractive that a psychopath, in fact all those Pick up artists guides are basically trying to teach regular folks to act psychopathic to pick up chicks.

As a male I tend to be attracted to crazy chicks with an edge too, but I think for women it's even stronger. Most women are totally bedazzled by psychopaths, even those who would hate to admit it. A psychopath can easily lure them with their inflated egos and enchanting disdain. There's no way to make people need you than to treat them like crap with confidence.
