I agree with what Erv said. My Dad started taking me ringneck and deer hunting with him when I was 6. He never said anything when I broke sticks or ice on puddles or shouting - "there he is Dad, shoot him, shoot him"
Just calmly explained why those weren't good things to do... I think the most important things (notice I didn't say these were all) that he instilled in me were firearm safety and respect for all animals and the land. Other than chipmunks (sorry Alvin), which were almost to epidemic populations and snakes, every animal I've ever shot has gone on the table.
