The devil cant! You are absolutely right. Read the book of Job. Everything that the Devil did to Job had to have Gods permission. Now as sick and twisted as that may sound, the bottom line is that the Devil had no power to do anything to Job without gaining Gods approval. So any good Christian (God save me from your followers) who says the devil made them do it, just acknowledge that either they used their own free will or God let the devil have his way with them. I would think out of the two choices, the choice of free will would be more likely. Unless of course, your name is Job
