Apocalypse: the Law of the Black Forest

In the apocalypse, everyone will be a hunter approaching you with a hidden knife for food. Whether it's your relatives or familiar friends. When they are hungry, they will transform into demons and rob you of the food you need to survive. If you don't have food, you are food in their eyes. In the last days, other people are hell. All kindness is worthless in the face of need. Your soft-heartedness may not necessarily bring gratitude, but a more cruel betrayal.
