Antman On Satan

An interesting sidenote: Satan could only have rebelled against a perfect creator if he had free-will. The point of God creating Man after his angelic host was that humans could love him with their free will. Satan could only rebel if he was compelled by God to.

That implies (some Jewish philosophers known as Kabalahists have said this to) that God is not all-good but actually a kind of yin-yang of Good and Evil. The origin of Evil is with him. This is definitely an impression I get of the Old Testament. The New Testament is kind of like a hippified version of the Old but that's my own opinion and can't be bothered to back that up.
