Disappointed in one Endwalker Aspect [SPOILERS]

[KizuyaKatogami]

Because in the end the Ascians would still be the enemies (since they basically want to destroy the shards) and Hydealyn would still be the one that is on our side to stop that. But SE could have easily let the Ascians still be the ones they were in ARR. They all could have been Lahabreas. Instead they used their time to make them, especially Emet, sympathetic in a way.

SE could have also easily made Hydealyn a purely good character, yet they even have her tell us that her actions were not kind. They could have said that the sundering was not her intention but intead they showed her conviction to do that in that one scene.

And about Elidibus and Zodiark: Well it would be the Ancients that would be dead without their actions. The one that fights for us is Hydealyn, so of course she would be seen in a more benevolent light than the ones that dont even see us as living beings.

No, we would be dead were it not for Elidibus sacrificing himself to help us time travel. We would be dead were it not for Zodiark shielding us from Meteion. The fact is they constantly talk about how the story isn’t black and white and both sides are morally grey yet they paint one side far better than the other and don’t give the opposing side the credit it’s due.

This entire game is about the gray of everything. Both of what you say are correct, and i don't think anybody disputes those. What is coming up to be disputed a lot is that Hydaelyn is an uncaring villain when everything in the game is showing that, just like Elidibus, Emet-Selch, and Zodiark, she was a good person put into a difficult position and made a hard choice that is controversial. She cared about people a lot, to the point where she was willing to force the Sundering to make sure people lived on. That act was cruel (she herself acknowledges it), but led to the current world the WoL and Scions know.

Her actions since then have been benevolent and attempts to keep people alive. To make her out as a complete uncaring villain is disregarding all the dialogue and lore by the writers pointing to the opposite up to this point. You can still make a horrible choice and attempt to atone for it, we've seen this time and time again in game with multiple characters across the entire story, with notable examples being Gaius, Fordola, Alphinaud (Crystal Braves debacle), Julius, the SAM 50-60 trainer, etc.
