Christians or others - How often do you kill and how much does it bother you?

I own a farm and hunt. So I kill for pretty much the same reasons you do, to eat, control predators, etc.. The only time it's ever really bothered me is when I accidentally hit an animal on the road. Once I shot a preg deer that made me feel kinda bad, but over all, killing animals doesn't bother me as I don't do it for the hell of it and I don't really get pleasure out of it in the sense that I only kill in order to feel that pleasure.
