By now (chapter 85) Eren doesn't necessary have to proof himself to be an ally of the Walled Humanity. Actually, this was a main theme of the Volumes 3 & 4, since then, he repeatedly prooved himself to be a crucial element of the Survey Corps successes.

Also Titans couldn't be necessary viewed as bad. As we were shown in Volumes 9 & 10, Titans were originally just ordinary humans meaning no harm. After they were transformed, they lost their ability of consciousness, so they simply cannot control their actions in the Titan form. While judging their intentions, we have to accept this fact.

Many answers are going to be shown in the next chapters of the manga. I hope that the origins of the Titans would be further explained as soon as possible.
