i think whether someone should pass on such a deer is totally differnent in each situation. One person who has hunted for years may have shot deer like the two pictured and then another individual who just started hunting may have never taken a buck. With the latter.... I would be fine if a friend of mine who just started hunting or never had any real luck harvested one of those bucks. And by no means does passing on these deer mean that 100 yards or 500 yards through the woods another hunter won't take a pop at them.
I'm not saying I would or wouldn't, just saying I think everyone would have a different reason for taking or not taking a shot. I've been hunting 12 years and haven't harvested many bucks, so it would be a toss up. I will agree that the first deer looks more like 2.5 and the stockier one is around 3.5-4. I'll say one thing, that second one is a hoss!
