Yes, I contemplate about the same and it drives me nuts! Lol, speaking of which I keep wondering if we were meant to simply eat fruits and nuts. I keep wondering how many I kill every time I walk or when you dig for building a house for instance. Someday if I found roadkill, I might consider eating it.
I agree that if you can kill the animal humanely and eliminate (?) suffering, it might be a good alternative.
One of these days I'm hoping to experiment in our lab on a project growing meat from stem cells. Wonder if it would be ok to eat that?
