Yah, totally my fault when I present situations like the one I described (that was a literal transcription of a situation that happened in one of my games). When there's absolutely no reason to attack someone and yet the player chooses to do so, it's absolutely my fault, no doubt about it.
I dunno, I grew up in Texas, and that was all murder hobo, all the time. Then, moved to California, got a bit older, and into a much more diverse crowd, and that was murderhobo only *some* of the time.
I totally see were you're coming from. RPGs are a way for people to fantasize about things they can't do in real life. It's an escape valve.
DEEP THOUGHT TIME: We are *violent* creatures. Civilization forces us to be nice when, deep down, there are many people we encounter that would greatly benefit from getting punched in the mouth a
lot more often. Murderhobo D&D is some people's way of coping with that.
I mean, I live in Europe. You want to know the equivalent here? Eurovision. The cheesiest, most disposable pop music in the world becomes the focal point of the nastiest, vitriolic nationalism every year. It's absolutely hilarious. It's the stupidest thing to get angry over, and I think that's exactly the point; if everyone blows off that steam on the music, then there's less chance of a WWII redux.
So, sure. Murderhobo is absolutely a thing, it can be kind of annoying, but I think it's perfectly harmless, and if people want to be that way in a game, cool - create another explicitly non-murderhobo group. Plenty of other people gave great advice on that.
Wise choice. There's a reason why Australians survive Australia...
Shame about your baby though.
