I think pale damage principle having two Abno represents The contradiction of position of "God" and the fight between two of them.
A God will always have an adversary, a all loving god will be called uncaring, a God who only protects a few will be called biased, but the position of god cannot be hold by both of them because they will disagree on everything.
God cannot be both. So the two fights for the position.
So there will always be a God and there will always be an adversary to fight said god...
The one who wins will become the true god and the one who fails.... Well, the position of the persuading devil is always open.
This is a cycle between two of them. It can never be a singular pale principle, because the two of them constantly cycled through the position.
at one moment, whitenight will be the god that everyone wants to pray to and at the other, the one sin and hundreds of good deed will save everyone from the hell that Whitenight brought forth.
At one moment whitenight was destroyed by his sins... And at the other Moment, The one sin and hundreds of good deed did not bother to pay attention to the plea of a heretic.
Two of them cannot both be god, so the position of god will always cycle between them, either because of negligence, pride, or the power of humans...
But there will always be a god, and there will always be an adversary, ready to topple said god.
