The honest truth is that right now, I don't have to hunt to survive. That still doesn't mean that I kill for no reason. I eat every game animal I kill. Even if you hunt and you can't use all the meat, maybe you could donate it to a local shelter or give to someone who could use the help. I know that there are programs around here that allow hunters to share their animals with charities, so there may be one in your area as well. You might also learn to fish. Learning to fish is a little easier than learning to hunt (IMO), and I have found that it is sometimes more productive than hunting (at least as far as getting something), but you can also throw them back. I release almost all the fish I catch, only keeping those that I want to eat or the few that get injured. I use slightly large hooks so that the fish has a harder time swallowing it.
