The end of Dr. Faustus

In the end of the story I'm not really sure I can say that Pride killed him.  It was just the fact that he kept wanting more and more knowledge which I suppose could be a pride thing but it was just the fact that he signed his life away.  It also ended up screwing him over because he ended up doing nothing with his new found powers. I'm not really sure what to think about this book yet--I think because I was waiting for some crazy twist at the end and nothing happened haha.
