As he becomes more dangerous to the people around him, he is the true monster of this story.
There is two books in this series, the first came out in 2005, the second in 2011. The way the second one ended highly suggests there will indeed be a thrid one. The movies - like the books - will consists of two movies, and most likely a third as well. Although the second one isn't quite out yet, it is official.
