The Murderhobo

How do you guys deal with the 'ecks dee I overkill this innocent person' characters?

>GMing home brew rules lite system for group of irl friends.
Two played dnd a bit before. No real problems here.
One completely new who originally wants to just meme with a 'frog that can cast magic'. Get him interested in setting enough that he makes a cool demon worshipping guy who's basically a debt collector for his master. Plays pretty well considering he's new.
Two people who say less than ten words between them for the whole session, just listen to the whole thing no matter how I try to involve them. I dont mind as we all are friends ooc and they dont exactly detract from the experience for the active players.
Finally a guy who in his own words wants "To just murder shit and be powerful". This is his first rpg experience, but he's so hell bent on murdering literally anyone considered remotely bad. I'll call him B.

Quick summary of first two sessions, party all happened to be sleeping in a tavern in various journeys, town attack by ghouls, party agrees to remove infestation from the nearby castle for a moderate reward.

>most characters were going to do it out of their own safety but B and one other was gonna just leave the town to its own fate and save their own skin, so I invented a reward to keep the party together.

Turns out ghouls are attracted to a vampire trapped in a prison cell in the castle. In my setting vampirism is a disease (ohooo original) so the party decides, after some hesitation, to release him.

Vamp bro is thankful, says he was a prisoner of war and got infected in the cell. Was going to go back to his home town to see if he still has any family left.

Luck out a little as the party decides to help the vamp home.

>Third session, B is a little bored as last session was a lot of discussing in whether to release vamp bro or not, conversations with vamp bro, and very little combat.

1/?

Noteworthy: B plays a gnome in a steampunk mech. Its all fine in my setting and mechs are my newbie friendly class, being naturally great at combat.
>Party arrived at nearly deserted village on the way to Vamp's town.
>Tavern owner explains since the nearby waterfall dried up, they had a large pest problem, and the wizard hired to deal with it only succeeded in making car sized monster spider's before disappearing.
>Town now doubly fucked by pests and giant spiders, most people moved out.

Again, most of party is down for helping out, but I had to to offer financial incentive to keep the party united. I'm totally fine if the party didn't want to help the town, but the issue was half the party was going to help, but B and one other were just gonna leave the town on their own cause they didn't give a fuck about the populace in b's case and the other players character hated spiders (making it a 50/50 split as
The two basically afk players didn't even speak)

Fast forwards a bit.

>Party has done some sleuthing and found the last known location of the wizard, a dungeon. Dungeon crawl ensues.
>Tunnel too narrow for mech to fit, but I have some things up ahead that only the B's gnome can fit through, so he still feel helpful.
>B decides he just wants to sit in the mech for safety and wait for party to be done in dungeon. Keep trying to describe distant noises he can hear from the party so he doesn't feel utterly left out despite it being self imposed.

Shenanigans ensue and basically the party accidentally destroys the spiders big nest, via overloading a magical ward lathe magician had set and freezing the entire dungeon.

They barely explored 1/3 of the place I made but again, don't care, the fact they nuked the dungeon accidentally with a trap meant for them made me chuckle.

2/?

Consequences.

That is it.

If he murders some fucker, call in the fucking guards. Make him a wanted man, with a nice bounty on his head. Good people won't associate with him, bad people will want the bounty.

>spiders flee for their lives while just attacking nearby shit in panic and starvation.
>Everyone has a good bit of fun defending the town with what remains of the villagers, but I make sure to mention the battle's horrific, half the town is eaten by spiders that night.
>B even has a fun 1v1 with a giga spider, pulls a support beam out of the tavern the party's staying in and javelins the thing, amongst other things.

Sessions about to end, but I add a little more.

>Remaining locals gather around (half destroyed mostly thanks to B) tavern.
>A little rudely voice their distaste at Vamp bro. Don't trust him, think he somehow contributed to all this spider shit.
>Rather than reason with suspicious, scared, ignorant peasants, B tells villagers he'll murder anyone that touches Vamp, and that they'll be staying the night, thanks.

Next Session

>Villagers have called in local vamp hunters in response to B (secretly of course), I let the party mooch around and repair/heal/socialise as they like.
>Group of villagers confront B when they him outside his mech. Ask him why he's defending what they believe to be an abomination.
>B replies with, and I quote.
" You Fucking pussies, you can't even defend your own town, I'm allowed to keep him alive cause I like him and you all owe me for saving you, Hah you're basically my slaves."
>Half the town still died and the rest of the party also helped defend the place.
>The grieving, angry villagers lash out at B for this, with Kick. B dodged and quickly jumps into his mech, running at the villagers.
"You're going to kill us for trying to kick you??"
Straight faced, immediate answer.
"Yup..."
>Villagers flee.

Its been some sessions since then, but its basically more of the same. No one else's property, penknives, or feelings matter to B (IC, dunno about ooc), he just beat a child thief to death with the corpse of his friend last session when a merchant asked him to help with the robberies the kids were doing.

3/4

As a GM? Keep killing him and not invite him to the next session. As a player, well, you're fucked unless your GM has balls.

So, what do? I'm 90% sure he's not that guying, more that he made a character who's an asshole and playing it, albeit I know he barely ever had fun if he isn't seeing action.

I've considered that, the issue is I specifically statted him really good at combat as he's new to the setting, so me bringing some character that can beat him as consequences just means it looks like I'm getting salty as a GM and 'rocks fall'ing him, when all I worry about is him disrupting the party.

Maybe I should bring some Npc that is killable, but still really Fucking good at combat as a 'warning '?

talk to them like a human being you limp-wristed cuckold

You see, that is the thing. You don't have to have some big unkillable guard roll up and kill him. You can put him yup against a perfectly normal guard that he will probably destroy.

What happens after that? He gets an even bigger fucking bounty on his head. People will come after him, guard patrols will recognize him on the spot. You don't have to make it so that he just dies, you can just make it so that his choices cause him to be severely inconvenienced. Maybe he can't show his faces in towns any more. You can make punishments that aren't "your character dies, get out of my house." so that he learns.

I don't.
I tell the players to decide as a group what type of campaign they intend to play and let them decide before the campaign kicks off what type of group they will be.
If they want to murderhobo their way through the world that's fine as long as they're all on board.

Then again at this point my players have all apart from 1 new guy played campaigns together and I know that they can play as a group rather than a bunch of random individuals that would never adventure together if given the choice not to.

You don't 'deal' with it. Not in an in game way anyways. Either talk to them like you have the balls to be sitting in the big boy's chair at the head of the table, or take it as a lesson and come to a consensus on what will and won't be acceptable next time you GM.
