Was he really a villain? I mean I don't agree with him shoving Renny off the boat. But it seemed like he was just trying to toughen her up. I've seen real abuse, and I can't consider that abuse (and by abuse I don't mean the least worst of abuse - which is pyshical abuse, but rather physical abuse combined with emotional abuse [which includes bigotry; so the violence enforces the bigotry if you will]). He was an asshole to some of the kids and I think he deserved his death for that reason, most particularly the aspiring filmmaker, I just wanted to kick the professor's ass for that, so he deserved his death for the way he treated him! And I think the kid gave the tape to the girl in revenge for his mistreatment.
