Well, yeah Papyrus' battle is WAY easier than Sans', but he is literally the only boss who can't kill you (even Toriel can if you run into her attacks). 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...
