In my experience, what someone says they will do ( in the presence of others ) and what they WILL do if they think they won't get caught, are usually two different things. Ethics plays a role in every facet of our lives. Example; do you sometimes exceed the speed limit while driving, then when you see the police setting on the side of the road, you slow down until you get by them, then exceed the speed limit again when they are clearly out of sight? I think all of us are unethical in some way or another everyday. Not saying it's right, but that's just the way it is. I won't lie, If I were in that situation, and that buck walking up through the woods was a Booner, he'd be down right now.
I know it would be deliberately breaking the law, poaching and trespassing ( to go get the deer), but he would be hanging on my wall.
