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

[Absimiliard]

Opting not to use words with charged historical undertones when it is not necessary to not muddy the waters of the discussion is not employing euphemisms.

I've found the term omnicide far more accurately captures the crime. She did not single out a particular race, religion, nation, creed, or ethnic group. She killed everything and everyone on the entire planet except herself, Zodiark, the three unsundered, and a few of her creations. The eradication of all life on a world is outside the scope of genocide as a term.
