A theistic, universe-based, theodicy of human suffering and immoral behaviour

In what follows I offer an explanation for the evils in our world that should be a live option for theists who accept middle knowledge. My explanation depends on the possibility of a Multiverse of radically different kinds of universes. Persons must pass through various universes, the sequence being chosen by God on an individual basis, until reaching God's goal for them. Our universe is depicted as governed much by chance, and I give a justification, in light of my thesis, for why God would have people pass through a universe of just such a sort.
