What's the point with that quite lackluster story in Endwalker?

[kpxmanifesto]

What the Ancients were doing was dying, and the expansion's narrative theme was how precious it was to keep living, no matter what. The entire basis of that story thread was that the Ancients saw death (for themselves, but especially for non-Ancients) as no big deal, and Hermes (and later Venat) are the only ones who saw this attitude as a problem.

I personally don't see dying after having fulfilled one's purpose as morally grey, though. That happens to humans in real life too. They serve a purpose by working during adulthood, then they grow old and are unable to fulfill that purpose anymore, and then they die. I don't really perceive that as a moral issue. Sacrificing non-ancients can be a morally grey area depending on how you look at it, although I personally wouldn't consider it to be.
