I don't really feel that his work is "right" or "wrong"; I just fail to understand why the man feels he should do these things. (I like the splashing of blood all over the walls, though.) It's hard to get anything out of the "art" if you can't understand the feelings behind it, and I can't even tell what those feelings are.
If he told me he did it all to watch the reactions of the people around him and laugh to himself, then I'd be all for it.
As for the $15k, I'm just glad it's not my money.
