I understand what you're saying, Eros. When I was very young I went out with a cousin and my sister. My cousin had a BB gun. I had never shot any gun before. There was a bird on this branch. I aimed and shot. The bird fell to the ground. I was sick to my stomach. I never thought for a minute that I would actually hit it, but obviously I was trying my best. I have never shot any gun since then.
I can eat the meat, but I can't kill the animal. Unless one chooses to be a vegetarian, someone has to do the "dirty work", however.
