Said so in the thread title, Bob.

If I couldn't have continued my sneak off to the side in order to get a better angle on the deer, I would probably have taken a shot myself. Not the shot you took, though. If the deer was quartered enough that the arrow would exit between it's hind quarters on a behind the shoulder shot, I'd have aimed IN FRONT of the shoulder, just where the shoulder meets the brisket, trying to get the heart, far side lung for sure and hoping to snag part of the nearside lung. All the while trying desperately to avoid getting the arrow into the guts. I hate cleaning up a mess like that.[:'(]

I have to agree it was operator error and poor shot placement that were at fault, not the broadhead. Don't be so intent on putting your arrow behind the shoulder that you don't recognize where the vitals actually are, and how to angle your arrow into them.
