Don't believe in Abrahamic god, but if you did, would you be a satanist?

If the God of the Old Testament were real, I would probably have to make friends with Satan. I don’t think I could bring myself to worship a God that destroys cities, tells people to kill their children in order to show their faith, or floods the world causing little boys and girls to drown. I would have to support anything that was in opposition to that.
