Other than the points mentioned above a very disturbing fact is that Bella voluntarily chooses death (for love in the form of turning into a vampire) over life. Which normal person does that? It takes a certain level of obsession to make a person decide such a thing. Also, in the book I found Bella using Jacob shamelessly as and when she needed & not even giving it a second thought. A book which promotes selfishness & glorifies it too!
