I'm a bit confused as to who it is supposed to appeal to. Is this whole series created just to allow Christians to feel smug and get their jollies watching atheists and muslims slaughter each other?
Doesn't sound very... Christian.
It's an "I told you so" thing, better known as a "You're going to Hell, and I was right! That's what you get for not listening to me, er, God! Yeah, God!" thing. The whole book series, and the movies, are both insufferably smug in every way.
