I got no problem with girls hunting, although I hate how it seems in every photo she takes with her kills, the animal's face makes it look like it's sad or in pain.
Hunting should be illegal unless you own the animal or intend to eat it in a conversationally sound way, or its necessary for population management. Was the animal owned? Does such ownership come with a responsibility to maintain a proper population? Then it should be legal to gun down. Grotesque, but legal.
