Your question was fine. There's no reason you shouldn't have asked it, Curtis.
THIS HAS NOTHING TO DO WITH "ETHICS"- it has everything to do with common sense.
To everyone considering this as a shot to take:
If getting game at all costs is what we are here for, why not hunt with a firearm? In other words, if killing that critter is such an absolute must that you would consider a marginal shot opportunity because you HAVE to kill it, why not use guns?
Fawns? Who are you kidding? You shoot fawns enough that you would even bring that into this discussion? How many pictures of dead fawns have we seen on this site? Most people are not shooting fawns..they're talking about mature animals.
A normal big game animal's chest is certainly wide enough that if your chest-on shot arrow doesn't hit within a 3 inch circle, its certainly a good chance you will one lung that critter. Add to that the animal is facing you and can react quicker than your arrow can get to it! I don't know how many one lunged animals you've tracked...but in my life I've had a belly full, and I don't want any more.
Combined with personal hunting(and being in Georgia with 10 to 12 tags per season),our nine year old urban deer hunting program has allowed me to participate in nearly a thousand whitetail tracking jobs...thirty or forty of them have been one lunged, shooting at the side of the animal!
I can tell you that if one of our members took a head on shot, he/she would be on the street so fast their head would spin.
Respect for a living animal is always uppermost in the minds of most hunters I know- and in every hunter I share my camp with. And it shouldn't matter if its a fawn, a yearling, a mature animal, or a world record.
