You had gone through the underground showing mercy to everyone, but when you got to Asgore, he destroyed your mercy button so you were forced to fight. But when Asgore had one sliver of health left, your mercy button was fixed, so you spared him, but then… Asgore: R-really? Even after all I did to you? Your… sparing me? a circle of friendliness pellets surrounded Asgore and killed him, turning him to dust Flowey: Pops out of the ground You… IDIOT! Flowey absorbs the six human souls and becomes Omega Flowey
