One part that I have to add is that the RV driver himself was a victim of the old couple and I'd say it was the old couple that were the real winners. They were in a war against god and they did manage to breed sinners (including RV driver and Keller Dover and a Farther of the church) and make many people loose faith in god.
Loki named after the trickster god was the only one who got out of the maze fine.
Well said, it reminds me of something like the movie Seven, where the Spacey character makes the protagonists play their game.
