The unresolved problem with people's understanding of God and the Created universe in which we live lies with not understanding the principle of how God's will is accomplished. God, as creator, created humans to also have creative capacity. Harnessing that, maturing that and 'creating ourselves' as mature good humans relies on that aspect. Thus, God's vision is in fact a joint project: God's effort + human effort = accomplishment of God's vision. God fulfills his part, always. But humans sometimes do, sometimes do not. If a human fails in a responsibility required to complete God's work, then the accomplishment of that work is postponed, and the responsibility reassigned to someone later in the timeline. This is why it has taken thousands of years for the world to get to the point we are now. Joint operation. So no, the rape of children is not part of the plan. But yes, thinking every single thing is God's plan is an immature view of the plan.
