If God is the Creator of all things and evil is a thing, then God is the Creator of evil and He is to be blamed for its existence. No, evil is not a thing but a wrong choice, or the damage done by a wrong choice. Evil is no more a positive thing than blindness is, but it is just as real.
Peter KreeftHow you approach the problem of suffering depends on how you approach life itself. There are only two ways. Either meaning is surrounded by matter, or matter is surrounded by meaning.
