No wonder Asgore destroys your ability to show mercy to him. He does not believe, and will never believe, he ever again deserves it. If you kill him, he dies with a smile (I have not seen this for myself and I hope you'll forgive me for not looking.) He's never going to be anything but a murderer in his own eyes ever again, and he knows pretty well that Toriel will probably never see him any other way, either. (Yet still I can dimly glimpse the way for her compassion to win through, even for Asgore.) To kill _one_ person that way was bad enough, but _seven_? Seven unwitting victims falling into a trap? *sighs*
