I like that this is more than just saying "gods egotistical", just the fact that he asked that question to one of his retainers and accepted her brusk answer says that he isnt just an "almighty being" i like this ambiguity.
And we now know that being a sacrifice isnt just to die is to be transformed, it can be "good" or "bad" but like the monk said it is people that decide their fates, those past sacrifices clearly have a good and respectable life.
