Some of the most horrific acts of mass death have been conducted throughout our own history under the pretence of resolving 'inequality'. Often accomplishing little more than replacing one set of out of touch 'leaders' with another and inflicting starvation, torment and worse upon the populace.

As for the 'least bad' option, I daresay sacrificing a portion of the 'New Life' to Zodiark would have qualified as such instead of subjecting every single man, woman and child amongst the Ancients to genocide and bizarre 'tests' that were enforced upon them without their knowledge and consent.
