[i]Any society that normalizes cruelty to animals is capable of normalizing cruelty to humans. [/i]
Every society has used animals for meat, fur, feathers and more. Every society has also waged war and been “cruel” to people.
That’s different than normalized cruelty like, for instance, throwing a live dog into a kettle full of boiling oil as is common practice in Asian cultures. If you can do that to a dog, you can do that to a person. One could draw parallels to a lobster I suppose but I think crustaceans are different than dogs. If I saw someone doing that to a dog and there were no witnesses...yeah.
