Well, without the usual self-egocentric stroking that usually goes on with such a thread, I think by classical definition I'm a villain. No conscience, no morals, no care for anyone or anything around me, myself included? Yeah, definately villain. I know a lot of people are going to proclaim how "evil" they are, but until they truly don't have the things that a regular mind brings (like a conscience), they're just blowing hot air.
Aquired brain injuries for the evil (or complete lack of humanity) win!
