That red stuff coming out of him can't be ketchup because monster food is absorbed the moment it's consumed. And monsters don't bleed because they don't have physical bodies.

Sans will watch you push the world to its absolute limit and only fight you when there's no other way. He's pretty darn patient. Papyrus is a naive narcissist that truly believed that being kind to a mindless killer will make them change their ways. Also, they aren't the same person. Why are they even being compared.

Sans, Papyrus, Undyne and Alphys sweat. That's not unique. Toriel and Asgore have fur. Mettaton is a robot. They all eat monster food. That's not unique. They don't have physical forms, so magic is magic.

If he's bleeding, you're assuming he's human and that he has any use for blood in a skeleton body.

Almost every monster in this game is anthropomorphic. Undyne is a bipedal amphibian with anime proportions. Papyrus, another skeleton that is closer to actual human proportions - why not him? Does he not have enough mystery to him to fit your theory?

He does that "breathing" (you realize his mouth doesn't open, right?) thing in genocide only. He's juiced with DT, which probably isn't making him feel all that good. Probably like he's on the verge of melting. He doesn't move like that in TP. There, he moves around yoshi-style like Papyrus does. And he stands still.
