There is a time and place for censorship. If I was a parent, would I want my five-year-old child to watch something like Saw or play a game like Condemned? Hell no. But according to the original poster, this is an academic situation where a fifteen year old is the one not being allowed to read the book. That's just stupid. At that age there really is no good reason to not allow her to read the book in class. The author makes it clear that he does not condone the main character's actions at all. Besides, at fifteen a person has already pretty much developed their personality and morality, so not much can be done to change that. A parent's job at that point is to try and lead them down the right path but not yank them down the exact path they want them to take. That generally just leads to rebellion.
