This month I present for discussion....
March: Satan: An angel expelled from heaven; evil personified; the great adversary; inspires mankind to turn away from God; inspires mortal sins. From Greek Satanas, from Hebrew śāṭān. bef.900. (Islamic, Judeo-Christian, Satanic)
I don't necessarily see Satan as being "evil" in the western word sense. I view him more as a biblical tempter, making humanity prove it deserves the gifts, that for all the misery being human can bring exalts us higher than any other creation. I never had a desire to worship him, he wasn't my style...but once you get through all the media hype. he's a pretty cool cat.
