I thought God gave everyone free will which explains why murders and all such deviancy is still growing?
I think earth is being treated as a battle ground to show the results of being separated from God. I really do think that God has put a metaphorical fence around earth for the rest of the creation to watch.
It’s why God lets bad things happen, because He must if he is to show in unquestionable terms what can happen when a creation is separated from his Creator.
