Before the spread of the abrahamic religions the pagan tribes had no concept of absolute evil. Monotheism created absolute evil when they created absolute good. Let go with the theory that the laws of the universe work on polarity, if you have Devine good by default diabolical evil must exist. (As above of below) if the church's of the abrahamic gods empty and most of the world would be some variant of atheists or gnostic would that mean the end of satanism? The ideas or philosophies could continue under a different name for sure but if "god" is dead then satan goes with him. If we follow the theory of polarity.
