I don't have to look away from any of it and I haven't hunted with anyone who does. I'm killing something, I want to do it, I have fun while I'm hunting. But here's a story... Worst deer kill I've seen was when I was hunting with another guy--he put 8 bullets in a deer with his 243. I walked up to it first and it was still alive but I had no gun as I had no tag. I did feel quite bad for this one as he lay riddled with bullets. So I got his rifle and finished it off. 2 hooves barely hanging on, a neck shot (plus my finishing shot), several other meat shots, but no real vital shots. He was dead within minutes of the first shot.
There are much uglier ways to go. I work in emergency response care and have seen it.
