We take death into our bodies because we believe the myth that in the death of that animal there will be life resurrected in us. The truth of the matter is that it never happens. What does happen is that we clog our arteries, cause much strain on our digestive system, and we set up our bodies for a list of diseases in the future and of course the immediate risks of e-coli poisoning and other bacterial dangers of animal foods. We clearly create our own hell by contributing to the hell of other beings. It is really divine justice at work.
Life comes from life and death comes from death.
The equation is simple, the more you let live the more you will live. I will not deny that we feed off life on some level regardless of what we consume, but that is the difference, to live off live things and not dead ones. This goes for fruits and veggies too. Think about it, we are the only animal that cooks and processes the food we eat. No wonder we get diseases, and free roaming animals that are not influenced by humans do not.
