If it were revealed to me that, say, the Aztecs were right, their gods are real, and the One True Religion, then I believe it would be my duty to defy their will, and reject their plan for mankind. Power does not grant moral authority, even if it is the power that was used to make the world as it is.

Would I be brave enough to do it in practice? I have no idea, but I think it helps that I'm thinking about it beforehand.
