Hello! Thanks for any assistance in advance!

I am looking for a poem/story. Some of the story elements are: There is some sort of village of people. In the town/village some force (death, the devil, or a judge of some sort) is slowly killing the villagers. In the end I believe only the reader/POV character is left alive and realizes that something could have been done to stop this but they did nothing.

I know this is rather vague but I appreciate any help.
