So it goes like this:
Satin is bad, you have been told that since birth.
And he makes you do things God does not like. In principle, that is why he is bad, ok.
But God gets angry and sends you to hell because Satan, an angel made by God, and allowed to go bad, knowingly he will by God, got it in his mind to make you actually do something, which was bad in God’s eyes.
Then, when you go to hell, Satan is there again to punish you for listening to him?
