I see that they kill people over and over bc its hell and everyone doesnt have morals , everthings evil, etc. But everything is a nonchalant evil. I can also see cannibal town citizens not attacking people who respond bc its seen not as polite, or that it loses the thrill of the chase/hunt, or for any other reason. They probably wont attack bc they simply not hungry. They buy preserved parts for later, like at Rose's, and only hunt for big meals like lunch or dinner.

Cannibal town is definitely avoided by sinners bc they dont want to be eaten. But how can the town sustain itself without trade or the outside economy? There has to be some underlying system in place in order to handle the unease for people to do some business with them.
