this should be in interesting discussion.

^ here is some reference material

Satan, like Prometheus, gave knowledge to humanity by giving Eve the fruit from the forbidden tree. Because of Satan, humanity gained knowledge of good and evil, according to Genesis. Since we couldn't have possessed knowledge of good and evil before eating the fruit, Adam and Eve couldn't have known that eating the fruit was evil, so it seems a little harsh to punish them as severely as God did. Satan gave humans true capacity for moral judgment, unlike God, who simply expected everyone to mindlessly obey his orders.
