A large portion of the book is here online. I linked the page with the pig incident. It's not exactly as depicted but still pretty nasty even to me, and I spent summers on a cattle farm. Castration is a necessity but I never saw anyone start a faux-food fight with the testes and shit and piglet corpses as the piglet lay squealing and bleeding on the ground.
I'm gonna read up on a few of the other incidents described in the OP synopsis as well.
Everybody good, plenty of slaves for my robot colony?
