Hannibal Rising

What still bothers me is the police inspectors description of Hannibal as a monster. Does it make you a monster when you want to kill the people that ate his sister or for the way he behaves after seeing his family die and the people he cares about? Not that I think he's a good person either, but he doesn't enjoy torturing people or anything like that.
All in all my expectations for this book weren't especially high after having read the previous ones, but I still can't say that I enjoyed reading it. If it weren't for the fact that I wanted to read the complete quadrology I wouldn't have bothered myself with it.
