>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".

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.
