Well, as a family we do eat a lot of venison...in fact I buy less than $20 worth of beef all year if we have a good year (between all the game we harvest...or try to). We hunt for the meat more than the horns. If we have a good year, we donate to friends as well as to share the harvest (Missouri program).
Fawn is like veal!! Best venison you'll ever taste. I know there are people who kringe at the thought of people taking a fawn, but if it is what walks in front of me I will fill the freezer and not think twice. That is not to say I wouldn't have taken the doe in the same situation you described...I would have taken whatever presented the best opportunity for a safe, accurate shot.
I won't fault people for horn hunting, if they don't fault me for meat hunting...
