The devil as we know him from the bible, has not always been involved in religon all through history. There have been many gods at times that were troublesome but not as the devil is to a judeo/christian/muslim, the devil from the bible is actually a beleif taken from the Zoroastrian beleif and the jews sucked that one right up and made it part of their beleifs. Most of the pagan beleifs do not have a satanic type of god involved in their beleifs to blame when something does not go right. Some do have gods that are not always very nice, but not satanic. Eventhe Satanists do not have a god that is satanic. It's just a crutch for someone to use, I prefer to blame myself if something goes wrong,not some mythological god/fallen angel.
