But the other side(Reiner, Bertolt, Beast Titan, and Annie) doesn't know that. Plus why would/should you try to negotiate with someone that is currently trying to kill you, and has been killing your people for a long time? Regardless, even if it was possible, it probably boils down to both sides wanting power.

Plus there are things that haven't been revealed to consider. Some of the theories out there have tossed around the idea that the people inside that walls may be the offspring of the people who were originally forced inside the walls because they were bad people, so that was supposed to be a sort of punishment for them. Then there's the one that implies the Titan shifters outside the walls are intentionally using the people inside as some sort of lab rats.

So until we know why the people live within the walls and why the other side is after them, a peace treaty would be unlikely.
