The sad truth of this thread is that for many bowhunters, as long as a deer is within range, they will take the shot, regardless of the poor angle, light conditions, or the deer's state of alert. ALL of these things, combined or individually, can and will lead to a botched shot and an unrecovered deer.
The shot in question is bad on MANY different levels, the most obvious being the small bullseye that's surrounded with "bad shot" area, and the most basic rule of bowhunting that you NEVER draw on a deer that's facing you. That's like ASKING the deer to jump string. I know it's easy to do, I did that exact boneheaded move about 2 weeks ago. I realized this after I drew, and would not have shot even if the deer hadn't seen me draw.
If you want to be able to shoot every deer that comes withing range, then stick to gun hunting. Bowhunting is NOT easy, and that's what makes it so great.
My personal credo is to only take HIGH PERCENTAGE shots. This limits me a lot in the amount of shooting opportunities I have, but when I do shoot, it's with 100%....yes, I said 100%....confidence that I can make that shot. Have I gotten every deer I've ever hit with a bow? Of course not. Even with the best of plans and situations "doo-doo" can, and WILL happen. That's why I limit myself with my shots, because at least then I know I've done everything possible to the best of my ability to take a shot that I'm 100% confident in. This means that if my maximum effective range on a 3-D range is 25 yards, for HUNTING I reduce that by a third. That also means that if I'm not 100% sure of my "spot" on the deer (angle, light, branches in the way, etc.), I don't shoot. You can't call the arrow back, or have a "do-over". This is the real deal, literally life and death, and possibly a long agonizing death.
Part of the problem I believe is with some bowhunters who haven't killed a number of deer yet, and feel the pressure to get a bow kill. Some of it is plain inexperience, and some of it is just bad luck. All I know is that I've had some deer that I shot at that I had no business shooting at (mostly for the reasons stated above), and not recovering them torments me to this day. We owe them, and ourselves, better.
