And you've completely failed to understand that the third sacrifice, for the story to make any sense at all, has to be substantial to a level of moral ambiguity; it has to be something that would be objectionable. If the third sacrifice isn't a huge and dubious alternative of some kind, then the Convocation look stupid for not doing it earlier, and Venat's crew look stupid for objecting to the ethical alternative. Since I assume you don't think the Convocation are stupid, then the third sacrifice must be something substantial.
My view on that is 'if that requires sentient beings to be the ones being sacrificed, then that's what it is for you to consider the problem'. We don't know the contents, but we do know the stakes and responses; substitute whatever works for you in that context as the contents.
