Yeah, this is an important element of it. It was a homeless migrant worker. Back in the 80s, I remember there was some mild (and somewhat affectionate) social commentary about the term Murderhobo:I think it's important to remember what hobo means - it's not "homeless bum". A hobo is homeless yes, but he works for a living. He's a migrant worker. Adventurers are homeless sell-swords, ie they are *for hire*. They aren't brigands. They get hired by people to deal with problems, violently.
But if the PCs ended up at their doorstep, someone probably sent them, and that means they posed a direct threat to other, more peaceful/weak beings that needed heroes to selflessly put themselves in danger to end that threat.
