the powerfully brutal would organize to enslave the whole planet to serve their nihilistic co-operative objectives with no regard to justice or civility
Sounds like monarchy. I wondered, what would be an example of a 'nihilistic co-operative objective'?
God wasn't angry, He just cursed woman, cursed the serpent, cursed Adam, cursed the ground, planted a flaming sword and evicted them from the Garden...
Aye, he calmly cursed mankind to suffer pain and misery for thousands upon thousands of years. He rationally cursed womankind to suffer even more pain for thousands of years.
Its funny though, because Monarchy got its power from claiming it was given by God. Monarchies of the ilk you describe have a habit of starting revolutions.
When a government is made accountable for their actions to the people, it doesn't matter whether the people in power believe they will be held accountable in the next life.
