DOOM: Repercussions of Evil is a legendary piece of internet culture derived from a hilariously poorly written fan-fiction story posted in 2002. The narrative follows John Stalvern, a space marine whose internal struggle culminates in the infamous line, 'No, John. You are the demons.' This meme became a staple of early internet forums and imageboards like 4chan due to its surreal grammar and dramatic lack of logic. It is typically used to mock bad writing or to subvert expectations in a dramatic plot twist, highlighting the absurdity of a character's sudden transformation or realization.
