What does Lawful Neutral versus Chaotic Neutral divine interplay look like?

[Vahnavoi]

Floods are not "destroy the world and the people scenarios" they are "destroy most people but a select few" scenarios.

For practical purposes, a lot of people would argue the distinction is without difference. To go back to the point made by ideasmith:

If I lived in that universe, I would not want side good to have a conclusive win.

It's pretty easy to imagine a person who is not in the select few, or even just has doubts about it, objecting to such divine spring cleanings, even if on some level they acknowledge them as good.
