I'm just attracted to playing people who are ostensible unlikable. That's not to say that there's something in there that makes you care. It might be that you just find them so awful that you just can't stop watching like a car crash.
If you start to disrespect the character you're playing or play it too much...
I wanted to end my life so bad and was in my car ready to go down that ramp...
Sometimes I bust out and do things so permanent. Like tattoos and marriage.
