I don't expect anybody to watch my back, I don't care if others think I'm being harsh. My answer is HELL NO!
I've heard people say if you don't shoot you'll never kill anything. Yes thats true BUT IT DOESN'T MEAN IF YOU DON'T SHOOT THIS DEER YOU'LL NEVER GET ANOTHER CHANCE!
Sorry about yelling. You'll always have another chance at a better shot.
I hate Hail Mary shots, and the people who take them, they are not people who are concerned with quick humane kills. Some people might not feel this way, but on the same hand there are others who do.

Now that I'm through ranting, I apologize for yelling, again.
