I know others who feel the way you do, and they're vegetarians because of it. I disprove of industrial farming practices, but I do take a lot of comfort in the fact that I, personally, am not inflicting suffering on a live animal. If I had to personally raise and slaughter every animal I ate, I doubt I'd do much meat eating.

When I have the option of choosing meat from a cow raised and slaughtered ethically I'll take that one every time, but usually I have no idea of the provenance of a particular hamburger patty and that likely does wonders for my peace of mind.
