Some taboos will arise naturally, getting everyone to understand "don't do X because there's a significant risk you'll die" is harder than just going "X IS FUCKING HARAM AND GOD WILL KILL YOU IF YOU DO IT". Fedora tipping aside, in the context of that environment getting people to not do X is a very good idea, but less so when the environment's changed.
For instance, if you live in a land of at best small villages and harsh winters, raising some pigs for slaughter when needed is great. It's even better when you've somehow chanced on cooking it enough not to risk health issues. Piggy is your friend. You take care of Piggy.
Now, if you live in a hot climate and that sort of seasonal starvation doesn't really happen, and you don't do the boil stuff long time thing? Piggy will give you trichinosis. Piggy is FUCKING HARAM."
ObOnTopic: Starfire kept naked in chains only letting her crawl around a work site, steel ring gag locked in, forced to give relief over and over again, all day, every day. Used by guards too but they're encouraged to hurt her. She gets caked in dried fluids and dust and mud but is regularly used as a urinal. She sleeps with the two-dick space-Scooby Doo guard dogs - as long as she's perfectly submissive when they're done with her they're the only gentle contact with a living creature she has, unless a guard comes by and orders a dog or two to rape her. She's seen what happens to slaves who show gentleness and she forgives how they handle her.
Cut to Blackfire, who's made a deal with Starfire's owner. She's being serviced by two Starfire lookalikes, scarred and in full Stockholm Syndrome mode. She's being eaten out by one and massaged my the other, a wine glass in her hand. On the screen Starfire is sleeping in a fetal position. A dog has her neck between its jaws and is slowly fucking both her holes. Another has one cock in her mouth.
She really has to get some of those dogs.
