Never mind the biblical bit where god says he creates evil, you'll never convince the religious with facts and logic. They've got to feel it or realize it themselves.
The ancients had more sense: at least a capricious, emotional God similar to humans (like the ancient Greek gods) that does everything including create evil and allows the torturing of people on a bet at the high council reconciles better with nature.
My, what a benevolent god is god to bet with the life of his most loyal worshiper. A bet he looses... against Satan? And then god goes down and brags about his achievements to cow his tortured worshiper?
That actually fits with the days of Olympus quite well actually.
Also everything he lost is treated indistinguishably from property - e.g. he dismissss his wife to sleep with other men, he's made whole by being given more children (probably with some other woman/en), as if having more children would replace the children you lost - it's an insane piece of text.
Also, slaves, I mean servants are all virtually identical, right? Not like you can get attached to people who are just servants.
And god's divine plan for all of those people goes out the door as soon as Satan is like, "Is this one person really faithful though? If I take all the things you granted him, will he still love you?"
But a good representation if god existed, we'd all be toys. God would've planned all this from the start with his omnipotence when he set all the pieces in motion like an enormous rube goldberg mess to torture people for no reason. Create evil indeed.
