If the killing is done properly, there is no pain. Consuming an animal for food is not the same as torturing an animal or extended suffering of the animal for our amusement. I am tired of self righteous vegetarians or vegans preaching that sentimental stuff. Even animals themselves hunt and kill for survival. It is a natural cycle of the ecosystem. Are you going to preach to lions, snakes, cheetahs, spiders, etc about this too?
