As I get older, I just feel bad about doing it. I've always felt that a cow or chickens life should be valued as well and I feel terrible eating beef, chicken, fish whatever. I've tried to be a vegetarian multiple times, but never feel quite as good and don't stick with it. Am I being overly sensitive? Am I just an animal as well and it's no different than a predator eating its prey. Would you want an alien or a superior being showing you mercy if humans became food?
