Im really glad to see someone who understands that what Eren did can be correct while also being tragic and awful. Most reactors just take the "genocide bad, Eren bad" super safe take while ignoring the fact his race was actively being genocided. Even the Marleyans admit its their fault, its the worlds fault, not the Eldians fault. The Rumbling is a direct reflection of their hatred. Its also really nice to see you seem to understand the meaning behind the ending and Erens motivations and dont just hate it for being as extremely tragic as it is like most people. A lot of people really seem to hate that Eren is still a vulnerable human despite all he's done and what he's become. I think it makes him extremely relatable and real.
Also Udo says that Marleyans are Even Soft treating the Eldians, and Annie says that MARLEY, is the "only shield for eldians" that only speak TONS of things about how the eldian descendants are treated
He even tried to rationalize it within himself, even agreeing with cynical POV that the Paradis should be exterminated before mankind as a whole yet he couldn't accept it, which means only one thing. There was no salvation for the child that was Eren Yeager, therefore he made the full-scale Rumbling the only viable solution in his mind. To me, the ending revealed what kind of man Eren was. Always pitifully vengeful, always letting his emotions rule over him. All in all, pathetic human being.
It's not black and white, but I stand against Eren on this one, Eren was the one fueling Marleyans' sentiments of "damn...these Eldians are dangerous" by doing that attack on Marley...had he fucking staid put and let Armin go down his diplomatic route, maybe, just maybe there could have been a peaceful resolution and we could have avoided deaths like Sasha and Hange for example, not to mention the millions of innocent bystanders that died during the Rumbling. I get why he did what he did, but he did it out of vengefullness while trying to disguise it as trying to protect Eldia...no, he just wanted to inflict the pain he went through ten fold on Marley.
"he did it for y'all" naah...he did it for himself...the true scout regiment could have figured a diplomatic solution hadn't Eren go on a rampage....hell, a fuck ton of the good ones wouldn't be dead if Eren had just trusted on Armin for once....
