It is also entirely possible that Zeke and the other Eldian warriors from Marley have their own goal separate from what the Marleyans want. The warriors may secretly be good guys only pretending to be working for Marley. There's already been plenty of foreshadowing to tell us that the warriors aren't the real enemy.

Maybe they want to try to reason with Marley once they get the Coordinate, saying they can dispose of the titan powers for good so there's no longer need to fear/persecute/eliminate them anymore, and they may also ask Marley to just let go of what happened a long time ago. And if they can't make peace, they'll have no choice but to fight the Marleyans.
