I'm glad someone pointed out that Satan is actually not the Ultimate Source Of All Evil in the Bible.
I'm a little disappointed that no one's pointed out that God's "omnipotence" was largely a RetCon on the part of the New Testament authors. If you assume that Yahweh is LESS powerful than most of the other Elohim (and you keep track of when, in the original book, he was referred to as "Yahweh" and when he was referred to as "Elohim," which is the plural for "god"), then He comes out of the Torah looking resourceful and well-intentioned, and the narrative makes sense. If you assume He's omnipotent, then you run into theodicy problems from day one, and he looks like a petty, hypocritical tyrant.
