Is the Abrahamic God really Satan?
If I were Satan, and I wanted to lead as many souls astray as possible, I would claim to be a mighty, omnipotent and unconditionally loving God. I would tell my people there's only one way, and it's mine, and all other ways are false. I would tell people they needed to convert everyone to worship me so they could save their souls. I would have them torture each other in an aim of converting them all to my religion. My religion would publicly preach love and forgiveness while in practice it would cultivate hate and prejudice.
All I'm saying is if I were Satan, all these modern totalitarian religions claiming to hate me would be working exactly as I designed them to.
