Papyrus is a Lethal And uncontrolled Royal Guard commander and he cares little about the well-being of other monsters, and will not hesitate to slaughter anyone just to set an example. He will also kill anyone who threatens him or Sans directly while being sober. He does seem to take threats very seriously, so he isn't insulted commonly in Public. He does seem morally fine with treating others brutally. he is rude and strict even to children. papyrus and sans are skeletons.
