I agree killing and eating an animal per se is not animal cruelty. E.g. If I'm being attacked by an animal, I will protect myself. If the animal must die, then so be it. I would consume its body, too, so as not to waste it. But, if you had absolutely no *need* to harm an animal, would it be wrong to harm the animal? As we see with the last link in the description, we have no *need* for animal products in our diets.
