God is a narcissist. His very first commandment wasn’t “don’t steal” or “don’t kill” or “don’t be a dick”, it was “I don’t care how many other gods you worship, so long as you like me best”.
God refused mankind the knowledge of good and evil, and then bitched at mankind when they didn’t obey him. How could they have understood betrayal when they weren’t allowed to know that betrayal was bad?
Satan on the other hand, encourages us to learn. It was He who directed us to the Tree of Knowledge. Lucifer, as he is commonly known, means Light-Bringer.
Satan didn’t rebel against god because He didn’t love god, or because he was too prideful to bow down to mankind. On the contrary, He saw mankind as something that god was treating like crap.
It is god who casts human souls into Hell, just as he imprisoned Satan there. Why would Satan torture the few souls he is allowed as company? It is god who condemned humanity to painful childbirth for the actions of one woman, actions that only occurred because he wouldn’t teach us morality and ethics, yet expected to us live morally and ethically anyway.
