I mean if you own property and keep a small amount of livestock you're gonna get varmints.
We live rural, we keep chickens, ducks, couple Geese, few Goats and a few Pigs, nothing fancy, and I try to be as live and let live as possible, I wont go out to shoot critters unless they're getting be a real nuisance, trying to get into the food stores and stuff.
The only exceptions I make is rats (obviously, gotta keep vermin down) and Feral Hogs, 'cause those bastards are destructive as hell and they're literal vermin, they breed, well, like Hogs, and you have to keep their numbers down. Them I hunt all year for fun.
Nick never struck me as a country boy though, he may have property but he's a trust fund douche bag, he has no feed stores or birds to protect, if he's brutalizing skunks and raccoons he's doing it because he's a piece of shit sadistic fuck.
