Pimpin, I have never known a hunter who didn't eat their kills and I've known a lot, so it is completely wrong to say that hunting is killing just for fun or sport. What you are seeing is an immediate and incredibly humane kill for food.
I know it's easy to deny that the Turkey you ate on Christmas day was never actually alive because it came from the store, but in fact it was. It's fine that some people don't have it in them to hunt themselves, but it is just as fine for any hunter who is responsible in fast humane kills and eats their game.
