My role in society, or any artist's or poet's role, is to try and express what we all feel. Not to tell people how to feel. Not as a preacher, not as a leader, but as a reflection of us all.
With any part you play, there is a certain amount of yourself in it. There has to be, otherwise it's just not acting. It's lying.
We all want to live forever, but we don't want to suck blood to do it, right? I think people like to have these deep moral questions that don't come up in real life.
