salt great point, the first time i did it the women was crying like crazy, she was 150-200 yrds past the deer, at that time i'm kinda glad i had a knife instead of a gun, i walked back up to the car and assured her that the deer was dead, she was shaking like a leaf, she did not have to witness any of it, i called her dad, him and his wife came and drove the two vehichles away, not really sure what effect shooting the deer would have had on her[&o], but IMO i feel most people don't want to see any animal suffer anymore than it has too.......
BTW i know this is a tough one, as i have done it a few times, not something you enjoy but sometimes needs to be done for the sanity of all involved, just think about how much worse you would feel if you left the deer struggleing to flee, and dying a slow and painful death, as in hunting and any other life lesson, that involves life and death, you would try to make it as quick, ethical, practical as possible, at this point you'd be doing all involved a favor
again this is just MHO
