I've always subscribed to the idea that Lucifer was the good guy that tried to overthrow God but lost. He got A THIRD of the angels backing him. That's not insignificant. Shit was going on and people were unhappy.
Even though the Bible is written by the victor, it somehow still manages to show how fucking evil God is.
The Abrahamic religions and their followers are completely nuts or simply just don't know much about their faith.
