Undertale spoilers
@kara_dreamer@witches.town but yeah I run with the idea that Chara is narrator in ALL runs, that Frisk's actions either confirm Chara's twisted world view and continue their path towards demonhood (Genocide), or help Chara realise that humanity, and by extention, themselves, are not corrupt and evil and awful and don't deserve to be wiped out (True Pacifist), and the True Pacifist run is Chara's way of redeeming themselves by helping Frisk repair the situation they created.
