Satan is a being created by God imperfect and lacking. He is the disciple of void/emptiness/nothing/evil, and strives against The Perfect, The Whole, The All. He is not anywhere near equal to God, but he is not pure evil either. Evil is anything laking, and away from God. Satan fights against that which IS, but he is not complete nothing himself. Satan was the first to turn away from God and thus he is evil, but not the creator of evil. Evil can't be created because it is not of God and God made all things. Evil is anything not of God, thus Evil is void. God "IS", evil is "not". But, Satan himself is not pure Evil, because he was created.
An interesting answer. I've never thought of it in quite those terms. Something to ponder and pray about.
I wonder how that applies to current events. Most specifically: if terrorism is evil and pacifists seek to pacify or make "peace" with evil as opposed to fighting and resisting evil, then is pacifism evil?
