Interparty Conflict in OOTA Hey guys, first time DM here looking for advice on how to deal with a situation I've gotten myself into in Out of the Abyss. In order to cut down on the crazy amount of NPCs that made it out of Velkenvelve and simultaneously give my Half-Orc Warlock player a cool way to forge his pact with his patron (Mephistopheles), I had his patron appear to him in a vision, telling him to kill the Gruumsh-spawn (Ront) in order to prove his loyalty. After a battle with Kuo-Toa outside of Sloobludop, he made his move on watch and killed Ront, but rather bungled keeping it quiet. He gained his pact weapon, but his party (through use of Charm Person) found out what had happened. Later, one of the players talked to me about it and reasoned that, other than the obvious reason of not kicking the player out of the game, why wouldn't the party just kick out the offender? I honestly hadn't thought of that. Right now, I have four players and four NPCs left from Velkenvelve (Eldeth, Sarith, Shuushar, & Jimjar). He raised a good point that I honestly don't know how to answer... How do you deal with interparty conflict and murderhobo tendencies amongst chaotic neutral or even more "good" characters without metagaming? At what point does roleplay demand that someone attack another party member and it becomes a "you or me" situation? He is playing a lawful evil male drow monk who has made it his personal mission to bring down drow society (he sees it as cartoonishly corrupt and that their ambition is completely squandered on this stupid in-fighting). I feel like it's going to be hard to convince him to stay with the party in general without the reason of "well if you left the party, you're not really playing the game with us anymore." I'm stumped... And no I don't want to kick anyone out because we're all friends and/or roommates and not only would that be awkward, it was hard enough to get a group of four to play...
