This is a completely ridiculous question to ask. With Eren's motivation revealed, he's basically committing something similar to a false flag attack, but with the "attack" being a genocide of like 2/3 of the planet's population, in order to unite the races against him. That's a harebrained solution to a problem of racial conflict and if his actual motivation was ever discovered, it would his re-integrated patriots appear as conspirators and likely just get pogrommed. Also he literally kills most of the people on the planet in order to do this.
