The primary thing that I enjoy about Luke Cage is that he has a morality about him but it's conflicted. He's never sure what the right move is, but he at least contemplates it. He's a not a rash character. It's that thoughtfulness that I really identify with.
I try to keep my characters raising more questions than giving answers. I don't want to leave too much on the table. I want you to have your connection and your secret understanding of the character.
