I couldn't agree more!
After you've hunted long enough you will have a shot or two that didn't go just right. In some cases it may have actually been a sad ending with a suffering animal. Not that animals don't linger and suffer naturally in the wild... it's just that when it is the result of a not-so-perfect shot we should take note and pay attention to why it happened and how we can try to avoid it in the future.
Clean kills are the goal. But clean kill or ugly wound, there is a sanctity to life that we must respect, whether we hunt or not.
I've got no problem killing game. I just don't do physical or verbal end-zone dances about it. And I don't think anyone should. If they want to it's their prerogative, it's just not mine
I actually prefer to be alone when I come to a downed deer or other game. It give me a moment to ponder what I just did, ... why... and how I will make sure not to waste any part of the animal that I can use.
