It seems like everytime we have some idea on what the Titan Shifters ultimate goal is, they do something that completely alters it. So humanity did nothing wrong, yet they all have to die? I sort of get the feeling that whomever Bertolt, Reiner, and probably Zeke serve back at the Homeland view the humans in the Walls as some kind of threat in regards to something we haven't been shown yet. In all likelihood, it must have something to do with the "Coordinate" ability and the fear that it would one day fall into the wrong hands and destroy the Homeland. Reiner did state something along those lines when he saw that Eren did possess the "Coordinate" ability and immediately called him the absolute worst person to have that power.

If I had to make an educated guess regarding Reiner's situation, here's my theory, though it will probably end up being completely wrong; It's been established that Reiner suffered from multiple personality disorder with one being the "Warrior" trying to wipe out humanity and the other being the "Soldier" helping humanity. Both personalities have their own set of memories. What if after his head was destroyed, he ended up losing the entire "Warrior" personality along with it's respective memories seeing as that was the personality he was under at the time? Taking that into account, my guess is that after he fully regenerates, he will be under his "Soldier" personality and end up aiding humanity against Bertolt, which would seriously fuck things up on the Shifter's end.
