“Category zero. No incentive to kill other than the killing itself. A person who only wants the world to die. Every culture has a term for a person like that. The earliest reference I found was umilac. It’s an ancient Sumerian word that doesn’t have an equivalent translation. The closest thing we have is boogeyman, but that doesn’t compare to the implication the Sumerians were trying to get across. It roughly translates to bleeding soul. It’s the rarest type of human being there is.”
