Brutality is part of nature, its encoded in to the matrix of the world. I do not believe people would be vegetarian after watching this.
I knew a group of guys who worked at a slaughterhouse and they where the biggest meat eaters I even knew. I was told all the horror stories of their daily work, from the nail gun to being strung up by one leg.
Being a hunter is a part of the animal in us, as we are the dominate predator of this planet.
