Why would a just and loving omnipotent God allow Satan to exist? Isn't Satan supposed to be evil and worthy of punishment? Why would God toss all the sinning souls to him, so they can be tortured forever as punishment for a finite number of sins, without any possibility of forgiveness ever? Don't forget this is supposedly a God who turned himself into a person who preached forgiveness as the divine word to man. It just doesn't make sense, logically speaking. But then again, faith never seems to care much for logic.
