Misbelief ((Disbelief UnderFell Papyrus))

Inspired from FlamesAtGames Disbelief Papyrus, here is UnderFell Misbelief.
After losing the only thing he cared for, Sans, Papyrus decides to take his anger out on the only thing left in his world: the Human. And after seeing how strong the human is, Papyrus can't wait to finally fight someone who can put up a decent fight. But Papyrus will come to realize that, maybe, there was another way he could've stopped the human. He could show the human the one thing no one showed to it: Mercy.
