Dear M.A.P.
I believe it comes down to free will. God made it clear not to eat the fruit of the tree of knowledge of good and evil. And man made a choice. Without free will, can we really be alive? We could be alive like a plant, but not sentient. God didn't create man to be robots. He gave us life. So we have free will. It's not the devil's fault man fell. It's man's fault.
