I have my doubts that those who feasted on the innocent will ever reach salvation. If someone is that far from God only he can call them back. For many their eyes and ears have been closed and their chances very slim of making it. But we should still pray for them all as I truly believe if any of them do get saved God can use them to take down the rest. Either way the ones who don’t ever submit to him will surely receive the full extent of his wrath and go up in flames with their father Lucifer.
