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

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.

Well, first, I don't agree that working is inherently a human's "purpose". Especially not in a world like the one we live in at present.

Secondly, I really don't see how you're unaware of the difference between dying of old age and natural causes, and willingly committing suicide after reaching some arbitrary "purpose". What you're suggesting is that if, say, Scarlet Johannsen decided she'd served her purpose in life, she should just jump off a bridge and that be considered perfectly normal. The Ancients weren't broken, withered old people. They literally killed themselves while in perfectly sound body and mind. And even if they were old, I don't see old people as having no more purpose in life. But hey, maybe that's just me.
