How Can Something Be Evil in Itself if Evil Is Only a Lack of Good?

Questions about how Greg can say something is evil “in itself” if evil is only a lack of good, how Jesus could have had a fully-human experience if he never doubted, and whether all bad things that happen to us are spiritual attacks.
