Not to any responsible farmer. Respect in death as well as life.
>"Is it really worth having this animal suffer and die, when I could instead just eat a veggie burger?"
Yes. I have never killed an animal to eat and had it suffer. I kill sheep with a very sharp knife, and they're unconscious from blood loss before they feel the pain. I thank them for their gift once they're gone.

Whenever they get smart enough to do that to us.
Butt killing someone isn't respectful just because we say it is. If I kill you without you feeling any pain, it's hard to say I'm really respecting you, even if I say "respect in death as well".
> I have never killed an animal to eat and had it suffer
Have you ever purchased food that contained animal products? Because there is the overwhelming likelihood that the products came from a factory farm, which tend to be horrific for animals. Also, you say it _is_ worth it. Why? Why not just eat something else that doesn't involve killing an animal that doesn't want to die?
> Whenever they get smart enough to do that to us.
Ah, so not much of a circle is it then? A circle is reciprocal, and what we do to animals most definitely is _not_.
If I had to kill someone in self-defense, I'd also try to make it as humane as possible. There's no point in generating excess suffering.
> Why not just eat something else that doesn't involve killing an animal that doesn't want to die?
Because I am above that animal on the food chain, and it's my natural right to eat it. Why don't you go judge a lion instead?
> Ah, so not much of a circle is it then?
We rot in the dirt eventually, plants eat us, and then herbivores eat those plants. It's a circle.
Until someone gets hungry, and then letting the animal live a good life quickly stops being a concern, even though letting it live will result in exactly 0 nutritional problems (assuming a normal, balanced diet).
> we're no different.
But we are, no? We aren't dogs, right? Or lions, or deer, or doves, or elephants. We are humans, and can recognize moral worth and weigh the ethical concerns of a situation, such as "Is it really worth having this animal suffer and die, when I could instead just eat a veggie burger?"
