Don't feel bad at all. I once took a doe with a young one standing around and I can say I'll never do it again. After I took the shot (30-06 rifle) the little yearling did not run away and it kind of suprised me. When I finally made my way towards the doe, it ran off. It wasn't a fawn (no spots), and could survive without her, but I just had a sick feeling after that hunt. It was the middle of the season and I didn't have anything in freezer yet, so I took the shot. I can honestly say next time I'll let her walk. Respect is part of the experience...
