There is a scene in #FightClub where the protagonists (so to speak) threaten to kill a clerk and then let him go. Their takeaway is that tomorrow will be the best day of that person's life.
This logic holds up as long as you don't know anything about how people work. In reality it is more likely that person will just be dealing with PTSD. I am not claiming the filmmakers didn't understand this but I am sure a lot of the movie's fans have no clue.
