They are already here and they do not want to not exist nor be treated badly They are only here because we eat them. Look at the link I gave- nearly every mammal (counted by total weight) that is alive on earth is so because it has some use to us (https://xkcd.com/1338/ https://xkcd.com/1338/). If we stopped eating them, the vast, vast majority of them wouldn't be alive. Economics demands it. Nobody is going to use land to raise herds of cattle and just let them exist. So you have to make a choice between either the animal not existing, or us eating it. If you applied the same thinking to slavery many people would be outraged. But in that case, the people who were slaves could have paid their own way and been useful to society outside of being slaves. Cattle can't do anything else useful. Either we eat them or they're not around. We can be kinder to them, but we can't (within any reasonable interpretation of the modern capitalist society we find ourselves in) just not eat them and have the same number around. They have no other function.
