Killing or eating animals is an act of beasts. Stirs within the devil. Sorry. It spurs evil. Thus is truth - at least the metaphysical.
If you can cull an animal, or kill a human , and sleep well, does not mean you are any more well than a sick animal.
I've known humans, and I know beasts. The beast is better. It is unpretentious. It kills for food. Humans do 'cause they're just not any good.
Humans as a whole are but an unwholesome hole with a sorry ass. In short, a**holes.
