I can certainly see some anger issues in how his heroes dole out the punishment to the bad guys, but I am with Crocodilian's position. There is so little we (reliably) know about artists, and the choice, in and of itself, to pursue a career in art puts enormous economic stress on people. I have heard stories about other artists being either tempermental or just plain jerks...Dave Stevens for example. That doesn't make me bat an eye when I take in his gorgeous work.
People are fragile, imperfect things. All the more reason to celebrate when they are able to create beauty on paper, if not in real life.
I get where you are coming from, tho, Joe...domestic violence is hideous and a blemish on the world.
