Naturally speaking, killing an animal is no different than killing a fellow human. Human beings are by nature, cruel and selfish creatures. The thing that makes us different from animals, is that we have the mental capacity to choose to be civilized. If human beings are capable of choosing to not murder each other, why are we not capable of choosing to sustain ourselves without torturing and killing animals?Instead of a movie they need to watch cable. Force them to watch the Discovery Channel and Animal Planet nature shows.
