Mind you, this was for survival training. If I'm ever stranded in not-so-friendly territory with little or no means of survival, I'm not going to think twice about whether my survival is more important than some tasty, juicy critter's "feelings."
Well, naturally, but I am curious....how exactly do you hunt a rabbit with your bare hands? Just curious, because if you are talking about bumping it in the head, I presume you would not have a bow or a rifle.

Also, rabbits taste preety well >_>

If I know that it's done unethically, I won't touch it and make sure that any eggs that I buy are from free range chickens who are properly fed.
Problems are in the countries where the origin is not marked. Here we have a law for that, though.
