I feel zero guilt about eating meat. I feel zero pride about eating meat, I would feel pride if I killed it myself though. The natural order is irreverent. As is the question of if eating meat is natural. I subscribe to a incredibly subjective view of morality. It isn't defined outside of society/indaviduals. Secondly, each person or group you ask will have different moral systems based on their situation. I personally see "classic morality" or "the thing that society would want me to do" as the thing/action that I can take which benefits those around me the most are the most moral actions. How does eating meat harm society? Aside environment, I see nowhere that it does. And if I were concerned about the environment, there are many steps I'd take far sooner than stopping eating meat. So, if it doesn't harm anyone, why should I feel guilt about eating it? I don't give two fucks about inherent value of life. Life, inherently, is nothing more than collections of cells. The only thing that gives life value is the fact that we are life, as life, we like seeing life live. But, more importantly, we are humans, and are in direct competition (even if we have won a thousand times over) with every other life form on the planet. I want to see life spread to other planets, but not because life is valuable, but because I value life. I kill animals not because I see them as without value, but because the only time they are valuable to me is in the form of meat (or as a pet).
