Well it doesn't seem logical for you to try to argue the rights of vegetables if you don't really believe it's wrong to kill animals. I understand that I'm killing a living thing, but there's more death involved in killing an animal. You have the death of the grains they ate, plus the death of their bodies. That's reason enough for me. Like you said it is impossible to avoid killing something for food sources, but it is possible to kill less to eat more. And no one in their right mind would ever eat a lion, carnivores don't taste good.
