God withheld the knowledge of good and evil from Adam and Eve as dictated in the in Genesis of the Christian bible, but was he really so bad?
How does anybody know God is more moral than Satan? If it’s because the bible says so, then that is arbitrary and followers of the bible are basically just listening to God saying “I’m the good one, follow me.” If it’s due to observing actions and judging god’s actions to be better, then can’t we just use those standards to judge our actions, making god unnecessary? Besides, Satan hasn't even bothered authoring a book and telling his side of the story.
