GENOCIDE RUN (UNDERTALE)
Genocide runs in games can be pretty nasty, but the one in Undertale takes the cake with how utterly horrifying it is, and how permanent its consequences can feel. In the short term, it leads to the death of many beloved characters, and, in fact, the destruction of literally the entire universe, while in the long terms, all eventual playthroughs of the game are affected, so much so that even if you do attempt pacifist runs, there are some horrible events in the story that become unavoidable.
