In The Encounter (a movie I can't really recommend, due to the low quality acting and predictable story), Officer Deville is found guarding a road that has been closed due to poor weather conditions, forcing three vehicles to turn back to the Last Chance Diner, where the story unfolds between the occupants of the vehicles.
At the end of the film, Deville comes to the diner and informs everyone that the road has been re-opened, and that it's perfectly safe. The cafe owner, Jesus, says Deville is lying, but one of the diner customers chooses to trust Deville, leading to his predictable demise.
My question is: Why was Deville guarding the road in the first place? If he wants to deceive and harm the travelers, as is clearly the case, why was satan, posing as an officer, guarding the road?
It's quite possible this was simply another oversight, but the movie is clearly an attempt at allegory. Was there something more meaningful going on here, that I didn't catch?
