Except that isn't how Rejoinings work at all.

Yeah it is. The shard is destroyed, and the ultimate goal after all the shards are destroyed is to sacrifice everyone left.

Venat needed Zodiark, she had no plan to stop the Final Days without his aetheric barrier. She also needed him to restore the world. There's a reason she doesn't become anti-sacrifice until conveniently the third one.

The one where they're planning to sacrifice others instead of themselves? Yeah, that is a bit of a turning point.
