I like the idea that Lucifer (light) loved God so much and he felt betrayed when God created Adam and Eve, like he was resigned to the back burner. But then Lucifer shows up, like in Job, and is rather friendly with his old buddy. So much resentment. But Lucifer is needed for balance, for free will and choice, and the true crime in Eden was blame. Passing blame. Not taking resposibility. The snake made me. Eve made me.
