eta: Perhaps not a feeling of guilt, so much as a remorse and empathy and understanding. Doesn't keep me from hunting, but I didn't have that when I was younger.
Strangely, I'm right there with you on that. But I also agree with sandbilly. I've often said that things like planters, plows, seed, crops and feeders are the tools of the farmer and a hunter has no need for those things.
