Even as a meat eater I’m pretty shocked that this recognises them as sentient and yet does not ban their slaughter (aside from boiling them alive etc). Maybe I’ve read too much science fiction, but eating sentient beings seems Bad.
So long as they aren’t in physical pain during their life, I don’t think animals really care or even understand their situation. For instance, a bunch of cattle don’t wonder about how their lives would be better if they were free range. They just live in the moment with no concept of “a better life” or “freedom”. We project our feelings on them which they don’t have the ability to reason about.
Physically hurting them during their short lives is wrong because they do feel physical pain. We shouldn’t scare them. But they wouldn’t even exist if they weren’t made for food.
