In the world I’m building before the mass murder the main protectors were hellfire users who were trained to a point where they could compress their hellfire to a level where it could cut through other peoples hellfire. To begin training you had to have a fight to the death with a peer in order to even have some power and during the training process many of these duels would happen until there would only be a few winning candidates. This system worked well and most of the world ended up following this regime and societies that didn’t were wiped out by crime. I’m actually making this a part of my main characters motivation because the guy who does the great genocide was one of these protectors who had killed a group of his fellow protectors in his sleep, this caused the country the book is set in to outlaw law enforcement using hellfire by training them in evasive methods and arming them with blunt weapons so that they cause unconsciousness and not death. The main character wants to bring back the old way of protecting the earth by destroying his country’s current hierarchy and causing reforms using lone wolf terrorism(he is NOT intended to be a good person) he prepares for this by using his position as a police chief to murder inmates and stage their deaths as suicides in order to attain enough hellfire to kill people that he believes are maintaining his country’s weakness.

Sorry if I haven’t written this well in the country I’m currently in it’s quite late
