The official dialogue changed the ending for me. Eren told Armin the same thing he told Zeke.
First letโs get some things out the way:
The Ymir stuff is still bad.
Eren simping for Mikasa is pretty cringe.
Eren killing his mom is weird (but not as bad you think, will address later).
Now, hereโs where the official dialogue changes things. Apparently, Eren actually did WANT to finish the rumbling. In fact, the answer he gives Armin in the official is literally the same answer he gives Zeke in the Paths chapters. โI donโt know... I was BORN like this.โ
So now things get really weird. It looks like Eren both wanted to complete the rumbling AND wanted to have his friends stop him/do a Lelouch. He also tells Armin he didnโt know if theyโd actually stop him or not.
It looks like Eren created a situation where either heโd commit omnicide or do a Lelouch and just decided let things play out. Itโs weird, but that is actually MUCH more consistent with his character based on what we saw in 131.
For the mom stuff, itโs not like Eren knew about it when he asked Reiner why he killed his mom. Remember, he didnโt know he made his dad kill the royals until he did. Anyone who says โbut why didnโt Eren change __ instead...โ is missing the fact that it was established that AOT exists in a predestination paradox back in the Paths chapters.
All of this to say, I donโt think the ending is good, just meh, but not nearly bad enough to ruin the series.
