Undyne describes him as "Pretty freaking tough", but is too nice to actually hurt anyone. It is a mystery how would his battle go if he went on us full force... Also, monsters are made mostly of magic, that's how he can walk/talk/function...

As for "Papyrus do you want anything" speech, I think it is just symbolic because Sans knows you've finished him... Toriel does not want to kill you because if you slow down or freeze the frame after you die and before the game over screen Toriel makes an oops face.
