In the book, the bad guys were basically vampires, but they could still talk, etc.

At the end of the book he gets captured by a group of the vampires, who have created a new society and are getting along just fine. However to them, he is a monster of legend, that kills them without provocation. Ironically he realizes that humans are "obsolote" and he is now the monster, not the vampires, and thus he offs himself.
