okay but like from context frisk did a full on genocide run already and beat it (or did they kill sans and stop there??? if that's what it is it can change the whole story...) and in any case our non gender boi Chara here obviously still cares for everyone but what do they want out of a completed genocide run?? Chara doesn't have a soul but every time we give Chara our soul in exchange for the world's recreation we still have power over our own body (until the end of the game) and if Chara isn't always in full control, what can they even gain out of it?
