murderdom 

Killing someone for a cause to end all the horrible suffering throughout a community, region or the world. Particularly murderdom is done on tyrants and bigots who abuse power.

Me: We have to commit murderdom on Donald Trump in order to save the world from total annihilation. He is an evil ruthless dictator that will stop at nothing to destroy the world.

MURDERMOST

MURDERMOST is a person who has a growing behaviour of killing more and more people.

I'm NOT certain officer, but, more and more people are being killed, more and more every month. We could be looking for a MURDERMOST man - or woman, about all this.

murderhobo 

In a tabletop game, a murderhobo is a player who murders NPCs indiscriminately. This is normally derogatory, referring to a player who totally ignores quests, dialog, backstory, trade, world building etc.

The term is most common with Dungeons and Dragons, but it can be applied to most RPGs where the player is allowed to kill most quest-giving NPCs and NPC traders. E.g. Elder Scrolls, Fallout, Divinity original sin.

DM: The sad little orphan girl tugs at Steve's trenchcoat to get his attention, and ask for help saving her pet dog from...
Steve: I'd like to roll a strength check against strangling the orphan.
Dave: I call dibs on the dog.
DM: You murderhobos disgust me.

An old lady crossed the street in front of my car and I got a murderboner at the thought of flooring it.

Shows like Dateline NBC, CNN 20/20, Forensic Files, Cold Case Files, and/or The First 48.

murderhobo 

The typical protagonist of a fantasy role-playing game, who is a homeless guy who goes around killing people and taking their stuff. The term originated in discussions of tabletop role-playing games by authors seeking to create games aimed at styles of play not supported by traditional games like Dungeons & Dragons.

Four murderhoboes burned down the peaceful orc village, killed every orc in it, and looted their corpses.
