wasn't it once imply that if a greater force exist over human, human will unite to fight against it. eren said that this kind of thinking is too naive, this may also be the reason his father inject him something that give him the titan shifter and coordinator power so that he can free the wall titan that are enclosing human like calves. the titan are probably created to control human and if the human tries to reach the truth (survey corps), thus the central military brigade and the anti-human 3DMG. and what if the warrior from outside the wall are from the an opposing party that are against this thinking and is trying to find the one possessing the coordinator power and also the ape titan so that they can set mankind inside the wall free. well given that they must sacrifice a great number of people lives inside the wall along with it. just like armin said, if you can't sacrifice something, you can never change anything.

p.s. just some of my thoughts. not sure if I miss anything out as I'm feeling quite sleepy at the moment. ~_~ -Brenda C.
