All that thing about "who's the real enemy?" is also addressed in the recent Attack on Titan ANSWERS:

Isayama: My editor Bakku-kun (Kawakubo Shintaro) asked me long ago, “Who exactly is the enemy of the protagonist?” To be honest, before he posed this question, I never considered it. In Star Wars, Luke Skywalker said, “Why are all my enemies myself?” - and then the film ends. The one Eren must confront is also that type of “self,” as well as those like Annie. Right now, Eren’s direct opponent truly doesn’t exist, but the developments from now will showcase the things that he must overcome.
