Heh. All I'm saying is that a universe has to be consistent with itself. Take the Aztecs pointless sacrifices.
But in a fantasy world it might be part of creation. If evil wins creation ceases to exist or everyone is dead or mostly. The fate of a few mortals vs fate of the planet/universe/creation.
A lawful good general might have to sacrifice a city or army to win a war.
A lawful good God might have to make that decision to sacrifice a city, a chunk of land, a continent or whole planet.
