A person needs to be sincerely, 100% repentant.
I guess.
That goes back to TBall's point. Do these people have a conscience? I don't know. If they do, how does that work? I've seen some pretty evil stuff IRL. Met some really bad people.
Were they 'given over to a reprobate mind'? Did they still have a spark within that God would have mercy on?
I'm just glad I'm not the one deciding the fate of their souls.
I don't have a problem deciding the fate of their corporeal bodies.
