You're not doing a whole lot to explain why there is nothing wrong with eating meat and breeding cattle. I can think of a whole host of reasons why it is wrong in matters of ethics and mercy. Who is there to advocate for the cow? We know cows feel a gamut of emotions just as we do. They are not insensate. Most humans, when given a knife or a captive bolt gun and told to go kill that cow on yonder would not. So we externalize the death-making to slaughterhouse workers who coincidentally also suffer:

There's really no good, ethical argument to be made for the killing of animals for food or pleasure. Did we need to do it once to survive as a species? Yes. Are we largely living in a post-scarcity world where those practices should now be challenged? Yes.
