Thank you.

Regarding sin, as I see it, there is no sin involved (although the behavioral mathematics are interesting). An immature state begets immature results. A child that doesn't learn how to walk => falls.

If a parent can understand that the child that falls does nothing wrong or punishable, I would expect a God to behave at least at the same level of wisdom regarding the immature state of humanity. (We tend to think we aren't immature, but we are. And we are definitely very far from from the enlightened-end of the spectrum...)
