This is just my idea that I've had for a while. So basically, it's a genocide route but you only do betrayal kills. After completing through the new home, you make sans believe he will be spared. You would attack them, but he would dodge. He would still believe in your lie for some reason and only fights to make sure he stays alive. As you kept attacking, he would slowly stop holding back till it was to late.
