I feel like we're all forgetting that Zeke is a bad guy, I've seen nothing to suggest otherwise so far. He took great pleasure in wiping out the charging soldiers, cracking jokes and not at all bothered by what he was doing. If you need more evidence, look no further than poor Mike who Zeke allowed to be devoured by multiple titans, all while mocking him.

Just because Zeke said Eren was brainwashed by Grisha, it doesn't mean he actually was. He's just saying that because they have opposite beliefs about humanity. Grisha was on the side of humanity, as is Eren but Zeke is against humanity and because he believes he's completely right, anybody holding a differing opinion is wrong. Therefore he believes Eren is brainwashed, he doesn't really care about Eren otherwise he would've given orders to Reiner and Bertholdt not to kill him.

I think Grisha (related to Zeke, my theory is a brother) was from the hometown originally and was given a similar mission to RBA but once he was inside the walls, he began to sympathise with humanity and fell in love, had a family, essentially defected. He then took matters into his own hands to change how things were but once Carla died, he decided to pass it on to Eren.
