I have a theory that Sans and Papyrus could be half monsters half humans since they are human skeleton monsters.

It is hard to say though since Papyrus dies almost instantly (before dying he gives you an speach on how he believes that you will be a good person eventually) as he slowly turns into dust.

Sans doesn't die inmediatly either but we never see him turning into dust, although we know he dies and disapears because his boby is never seen after the battle (When metatton runs out of battery we can see his body in the overworld).
