Yeah, logic says let it go, but every time I think about it my stomach twists a little. I just hope she died fast.I nearly got into a fist fight with a co-worker that refused to locate a downed dove he didn't hit squarely. I found and killed it (he didn't have the stomach to break its neck). I never hunted with him again.
It's good that you're bothered but let it go. 45 years is a long time. I'm sure you are an ethical hunter.
