Any actor is happy to be involved with something that's challenging, controversial, and not easily palatable. Things that are too dumbed down or easy to swallow are uninteresting... It's good when people have such a polarizing response.
I was lucky enough to have an older brother who shared the splatter flicks with me, and I had parents who were cool and involved enough in my life to allow me to see them. I think my folks appreciated that I looked at these movies as a creative outlet... almost like magic shows, if you will.
