I would let him walk, but that's not much of a barometer, as I don't shoot deer much anymore.
Having said that, I'd hazard a guess that 90% of the hunting public in this state would kill that animal at the first opportunity.
But here's this, from a good friend of mine: don't overthink things you enjoy doing. If you get a shot, your brain will tell you what to do right there in the moment, and most of the higher brain function you spend contemplating it now will not matter when it ACTUALLY matters. (please don't interpret this to mean that higher-brain function TRAINING and DRILLS don't matter...all I am talking about is the "launch button", and whether or not it gets pushed to start the mental program for shot execution)
I have pulled triggers I didn't think I would, and I've put the safety back on when I was consciously ready to "kill, kill, kill". Usually I could later figure out why...but I will admit that there have been a few examples when I never DID figure out why I let one walk. Anytime I've gone against the instinct, the regret has been extremely strong.

This deer is on a 160 acres of private land. I'm a meat hunter first but fill the freezer with does so can be a little picky when it comes to a buck. I let a 2.5 year old 10 walk last year only to have the neighbor gut shoot and lose it. Found it eaten by coyotes a couple weeks later. My guess is this deer is 3.5 and would score in the 130's.
