Did I just destroyed an entire city by accident?

Hey, I'm quite new to all this Kenshi stuff, and I was wondering:

In my playthrough I just discovered a city called Shark in the swamps, and there I may have accidentally trigerred some kind of gang warfare.

Now everyone is fighting each other in the city until falling unconscious, then get up and go fighting again over and over. Most sellers are either dead or crippled by now (the poor casino owner keeps getting attacked despite the fact that he lost his limbs :') ). So it was very fun, and I'm usually going along with what happens in the game, but it seems like the town fell irremediably to ruin and that's a shame because it seemed like a really interesting place to discover.

So what happens in this kind of situations? Do they stop fighting at some point or will they all fight to death? Are the sellers and other npcs replaced by other ones or will it become a ghost town with a few crippled survivors crawling on the ground forever?
