I've never been in a "survival" situation per se. Ya know, "have to" kill to live.
But where I'm from hunting (or harvesting animals) is a normal part of the rhythm of our lives. It's seasonal. We don't go around "killing" for kicks...at least not the majority of us.
Anything I've ever killed, I've cleaned (dressed) myself. Took it to a local processor and "lived" off the meat for months.
From my perspective, it would be almost second nature to take the life of an animal for food (with my own hands). I think if you go to any butcher, any market, any ranch, any grocery store, etc. to buy your meat, you should also be willing to harvest the animal yourself.
I almost think it's a bit hypocritical for someone to eat meat their entire lives and pay someone else to do the harvesting...but not ever be willing to harvest the animal themselves.
