I think that any being that has the power of choice that is less than God, will make less than godly choices, less than perfect choices. This is what allowed sin to enter into the world and all the evil which follows. On the other hand, if we didn’t have the power of choice we couldn’t love God— we couldn’t love one another—we would be robots created to say, I love you God, I love you God, but it would be meaningless. Therefore, in allowing man the power of choice which man must have in order to know God, in order to love God, and to love one another, that opened the door to the possibility of evil.
