HOT TAKE: Honestly Zeke's euthanasia plan isn't that bad.

Don't get me wrong, it is fucked up to a certain extent, but it's not that bad, especially considering the fact what Eren's real motives were, loads of more casualties could've been avoided. Yes, Eldians would be extinct after a 100 years, but they would live peacefully (unless the world says otherwise), there wouldn't be billions dead, and eventually titan powers would be wiped out. Besides guys, Paradis does get, well...Paradis go boom at the end, so what the fuck? Might aswell have gone with the euthanasia plan. If Eren only used 80% of his brain, things could've been different. Zeke's ideology is questionable, but my second rewatch of the show, i kinda understood him, Eldians shouldn't born to suffer. And the world shouldn't have to continue suffer at their hands through Marley aswell. And he was dedicated to it, using Reiner and Barcelona to get Eren, play a spible agent for Marley, dude was motivated. Geuss you could say he knew the meme "why are we here? Just to suffer." It's solid to an extent. But that's just my opinion.
