DC,
Sorry your Dad couldn't have been around to show you that hunting isn't something done to hurt animals for fun but I think you've learned that lesson on your own. I'm sure he'd have been proud of you. Now you've met people who hunt for the right reasons and you've found they are good people.
You seem to be asking for encouragement to hunt but don't let anyone encourage you or talk you into it. This is an extremely personal decision that only you should make because you want to do it. Call one of your new-found country friends and ask them to donate you a venison steak and a recipe for cooking it correctly - then cook it and eat it like Rebel said. You say you don't need the meat but this is like no meat that you buy. No steroids to make it grow fast, no chemical feed to marble it with fat, no preservatives to keep it from spoiling for weeks until someone buys it. This is meat that only you can make - no one will do it for you.
If you decide not to hunt - that's OK - you can enjoy shooting at the range all day. You can let your neighbors hunt your land and control the deer. I think if you shoot them just to protect your shrubs, even if you donate the venison to others, it will not sit right with you. I can't imagine you would put an animal to death and then remove it's internal organs and drag it out of the woods instead of putting up shrub protection.
If you do plan to hunt, please get very good with your weapons, stay within 75 yds. and know where to put the shot for a humane kill. Once you harvest an animal, share the meal with someone you care about. You may someday teach your son to do the same.
