Killing Games
Those movies about the people stuck under a dome that everyone wants to kill, and they never do, but everyone tries, and they just don't want to caught, so they try to turn them against themselves, and basically they do it as a response to the inevitability of being punished by God, and they cannot escape the feelings of remorse and guilt and so they just carry attempting to kill all the time, as it is the only thing they can do to not feel bad.
