Perhaps I should be clearer. FF14, like a lot of good fiction, use its setting and characters to explore ideas that relate to the real world. Ideas like colonialism, prejudice, camaraderie, and the meaning of suffering. These are ideas that, even if explored in a fantastical space, are quite relevant to the ourselves as human beings. A large part of the reason that FF14 has such a good story is that it handles and explores these themes in a mature way. Its not high literature but its pretty high-tier for the medium and especially this specific genre.
This matters because CBU3 is pretty clear that we as real world human beings are far closer to the sundered people of FF14 than the unsundered. No, you are not your character but you are still a flawed, imperfect being doomed to suffer and one day die. You have to find meaning in your life to get out of bed in the morning and a large part of what CBU3 argues is the meaning to life is the companionship that we form with others, not just of our kind but of everyone on the whole of the star.
It also matters because the logic used by the Ascians and by their defenders, that all non-Ancients are subhuman and not worth preserving, is the logic used by loads of real world perpetrators of genocide. You yourself literally equated people to monkeys and said that it would be better to kill all the monkeys in the world than the humans. Its a real short skip from there to some very, very bad ideas about the actual world.
Why aren't the sundered the rightful owners of their own souls? Why do they have to give them up for people who died twelve thousand years ago (incidentally those people can themselves only exist through even more mass genocide)? And if you're going to make the argument that the Ancients were there first therefore they own them in perpetuity, I have very bad news for you about what claim you or your home country have to the land you're standing on.
The problem with this is that the Ascians still had to pull the trigger. At any point, Emet could have stepped back and realized what he was doing was wrong. He didn't until we threw an axe through his chest.
You're trying to wriggle out of your own words.
If you want to claim you're just neutrally describing the sundered, you should probably avoid calling the condition of existence "disturbing".
