When we hunt or fish, we deliberately kill a defenseless being who wishes us no harm. This is a direct violation of the First Precept. It is absolutely forbidden to Buddhists. As to eating meat, we know that the only way we can obtain it is for an animal to be killed. Therefore, when we eat meat, it is our intent that an innocent animal should die to satisfy our addiction to flesh. And that underlying intention, no matter how well hidden behind a smokescreen of rationalizations will block the growth of compassion and create negative karma.
