If the Devil exists, then logically, since God created everything, it follows that he must have created the Devil too. So, the question is why would this supposedly loving God, who allegedly craves a perfect world, create the Devil at all - and if he did it in error why didn't he remedy his mistake by zapping that troublemaker into oblivion long ago - just as he remedied one of his other errors by sending the Flood? He can do anything he wants can't he? Mmm ... we have a problem here. I suspect that this God is lying to the faithful. He isn't loving, and he doesn't want a perfect world because he's a controlling psychopath who relishes causing misery.
