Okay, I can partially respond to this. (I'm a satanist, so don't @ me over this.)
First, we're using mortal definitions of good and evil, which may not conform to what a god would define as good and evil. Moreover, if you say that god's will is good, and that everything that happens is the will of god because that god is all-powerful, then everything is good because that is what god wills. That means that, yes, the rape of children is good, because that was god's will. If god created everything and is all-powerful, then this is a logical conclusion.
Second, you can say that god knows the outcome, but that we don't. We believe that we have choice, but god already knows what we're going to choose, even though we don't know until we make the choice. This is determinism. Under this model, god is giving us enough rope to hang ourselves, and we condemn ourselves to hell, rather than god condemning us.
Sure, but if there's a god, and if that god is the only one, then it doesn't matter whether you choose to worship them or not, because they have absolute power over you.
This is fundamentally the problem that Christians create with their concept of morality, i.e., all morality springs from god, and if it's god's will, then it must be good by definition.
