I'm sorry I took that out of context, but I've seen this argument quite enough: "Oh you can't redeem him because he wanted to destroy the world and kill people, and he's evil and bad".
He does not have qualities that could redeem him and make him into a Scion, for example, for that I agree, but as I have said before: he has all the personality and background to be an anti-hero. All of it.
I am not painting him as a victim, I am saying he was once a villain and he can become an anti-hero. I'm saying he has all the potential to be a great character, not a good guy, but still a great character.
If people are blindly defensive, you're being blindly dismissive of all that the character can still bring to the table. You're saying that the character should be trashed just because he didn't do anything big and meaninful in two expansions, while Ascians were the absolute same for ARR, HW and SB. Ascians were plain boring, just going "oh lord zodiark hohoho please come back lord zodiark, yes, let's summon primals to bring back lord zodiark". And then came shadowbringers and we were struck by "oh... maybe there's more to ascians than just making beast tribes summon primals".
You're saying that they have "qualities that zenos does not", but you're saying it NOW, after they had their redemption arcs, lol. I don't think you'd say Ascians had development and depth back in stormblood or even half of shadowbringers. We didn't know Emet-Selch had solid, loving reasons until we reached Amaurot, the last zone of shadowbringers.
I don't think you're being fair at your judgement when you say one character is more valid than the other just because they already had their development arcs. He's still in the middle, if not the start of his. Again, he will never be seen as an actual good guy like Ancients were, but that's not his role either.
I'm not being defensive, I just think you have the wrong perspective on the thing.
