Let it go. That is why the world has scavengers. We used to be scavengers - look it up, it is true. (watch out - here come the holy rollers) Now we are hunters. Just think about where we would be if none of the hunters in our past had left anything to be scavenged! You provided a great meal for a number of animals. You should be proud of yourself for feeling this way, but not hard on yourself. There are a lot of things that you are bound to do and see if you hunt long enough, and you just got to experience one of the uglier ones. Now dust yourself of and get back out there and shoot another!
