I think there are three types of actors. There are the ones that do the ego thing, which is "I'm never going to look bad in a movie, ever." This is mostly the action film dudes, like, "Nah, hell no. He ain't punchin' me! I'd whoop his ass!" Then you've got the activist type who bases their decisions in the development of a character on what it symbolizes to society - what the ethical code is. And then the third type is a true thespian who doesn't give a flying rat's ass what it is as long as it's deep, powerful, and painful, and they will dive in headfirst. I really respect those people.
