The existence of evil comes from one simple source: Direct disobedience of God. That only occurs when God gives the most precious of things, FREE WILL.
If I give someone chemicals to fertilize grass, and he uses it to create a bomb to blow up somebody, I am NOT RESPONSIBLE for building the bomb; that person is. Nor am I credited for starting explosives.
...yeah, sorry. But none of that constitutes a refutation of the "Rex Mundi" heresy.
Let's not foget here that Satan does not have a soul (angels don't have souls) and that Satan did not eat of the fruit of the tree of the knowledge in the Garden of Eden, hence he does not know the difference between good and evil... and something without a soul that cannot tell right from wrong is not bound by God's Laws (man wasn't before the fall).
So by your silly logic... Satan doesn't qualify as evil.
Also, angels as a rule are not bound by God's law, nor are they bound by the ten commandments... so whichever way you cut it... God created an immortal creature that doesn't know the difference between right and wrong, isn't bound by God's law, isn't bound by the commandments and has the power to lay waste whole cities.
That's pretty fucked up... that's like me giving a chimp a nuclear weapon... pretty evil.
Even aside from all that... look at all the evil shit God does in the Bible... surely that's just Satan masquerading as God?
Maybe I've hit on something here... maybe the one thing God can't do is interfere... only Satan can do that: appearing as an angel to ignorant Beduoins; blowing up cities; spreading plagues; ordering the deaths of children and babies... you know, all the shit SOMETHING claiming to be God did in the Bible.
By their deeds ye shall know them.
Yep, I'm convinced... logically, Yahweh and Satan MUST be one in the same.
