So, until the game itself confirms that the ancients would "sacrifice lives to Zodiark until no one was left to enjoy the paradise he would restore," I'll just throw this claim into the bin of baseless conjectures.
At the end of Shadowbringers, G'raha, when asked by Y'shtola why he still lives despite us having averted the 8UC describes the situation as an "unexpected development." G'raha and his collaborators had every intention to carry out a plan they expected would result in the complete erasure of all lives on etherys, as well as the remaining shards that were in no way made privy to any of their plans, just because they couldn't live a reality in which the WoL was dead. The lives of an entire existence, not just one planet, but all of existence across an entire universe, snuffed out just to save one person. Please explain to me how the ancients planning to sacrifice just a singular planets worth of life is deemed the single most deplorable act across the games history.
