RE: Losing the killer instinct ...
I have similar thoughts at times too! Not so much sadness or remorse, but more like "is the fawn old enough tosurvive if I take momma down?" I'm not one bit interested in taking a fawn down to see how good it tastes. I'm usually after a "shooter buck" ormore mature doe.
Short story: I once shot a doe during gun season who had that years twins still with her. After the doe dropped in the field, the fawns ran off. By the time I gathered my things and climbed to the bottom of my tree steps, both fawns were walking back into the field to check on mom. As I walked towards them, the fawns took off into the wood lot again and as I was sitting there cleaning out the doe, I could hear the fawns occasionally call to the mom. That was kind of weird...for a few seconds I was asking myself "what did you do?" LOL
