I'm not disagreeing with Cheeseskates saying that Sans thinks he will be back, because that feeling of dissatisfaction when you beat the Genocide run really makes you want to return the world(at the cost of your SOUL). But I do disagree with them saying that Sans soesn't fight you because he sees a glimmer of light in you. Well, sorta. Something similar to it. He probably really wants to kill you when you kill Pap, but he can't. He gets pretty mad, even basing his judgement on you off of the fact that you killed his bro, rather than your LOVE. It like, overrides the everything else to him(and it overrides the game's judgement too, if its willing to make Sans say something different even if Pap is the only person you kill).

Back to the point though, Sans doesn't kill you because you had shown a glimmer of mercy. And if you have the ability to show mercy when the game allows(with the exception of fleeing) at all, the game grants you the gift of "mercy invincibility". This gift is pretty much what stops Sans from fighting you, his main gimmick is that you don't have invincibility, so he can constantly do his 1HP of damage to you. If you had invincibility, he probably couldn't kill you. I think this might be why you don't get a neutral fight with him, even if he wants to kill you.

I also think that he wasn't trying as hard as he could in the fight with him(or in other words, he didn't feel like fighting you because he thought everything was in danger, after all he doesn't really care, right?).He does do difficult attacks, but they are all avoidable besides two. The first one is the last bit of his pre-special attack where he bashes you against the sides of the board. The second one is an attack when you Spare him that covers the entire Bullet Board. You might think to yourself, "why doesn't he just cover the Bullet Board all the time?" I think he only uses it when sparing because that shows him that you might want to go back and do things over, and he is just making sure that you truly mean it by sending you to the Game Over screen and telling you not to come back, as if he were a tutorial on quitting or something. The thing is though, he doesn't use it otherwise. He lets you beat him because he is such a nihilist, but he must have felt some sort of obligation to convince you to go back, but that wasn't enough to make him give it his all, I guess.
