Okay, let’s examine the Sans fight in detail.

Sans can betrayal kill us. Sans can sense our SOUL. Sans can teleport. Sans “bleeds” from the body and mouth a color that’s the same as his ketchup, Kris’ blood, and Kris’ SOUL. For the record, the Undertale SOUL color is FF0000, and the Deltarune SOUL color is ED1C24, ripped from the ending cutscene of Deltarune. When we beat Sans, our EXP and LV goes up, but not our kill count. Sans completely disappears when we defeat him. We hear the victory sound when we beat Sans. We only hit Sans when we don’t use the Fight HUD. Probably others, but this is all I got.

Technically, the ending to Sans’ fight is either a death or a flee. We’re not entirely told what happens when a monster flees from battle, but judging by the castle exposition monster encounters, the narrator doesn’t say “You won!”. So because we won in the Sans fight, that probably means we killed him.

So what about the red stuff? As I said, it matches the color of Kris’ blood and SOUL. But so does ketchup. Well, it can’t be ketchup, so is it blood? Ketchup colored blood? Ketchup colored blood that doesn’t have the same color as an Undertale SOUL? Ketchup colored blood that, in order to be consistent with Deltarune’s blood-SOUL color similarity, would have to have the same color as an Undertale SOUL? Ketchup colored blood that disproves Sans being an Undertale human? Ketchup colored blood that might prove that Sans is a Deltarune human ?

I’m rambling and speculation. Maybe when Sans got hit, ketchup splattered out of his mouth, giving the illusion that he was bleeding from two places. Or maybe Sans is a secret spy working for the human government to infiltrate the segregated monster population, explaining why he and Papyrus “just showed up one day” BECAUSE HE HAD HEARD RUMORS OF AN ESCAPED SOULLESS HUMAN CONVICT WHO HAD CHANGED THEIR NAME FROM CHARA TO KRIS I WANT MY STORY POTENTIAL NOW
