No Offense or anything dude ..... but get serious!!! Think about this people raise cows all the time watch them grow for years and when they get big enough go outback and put a 22 round right between the eyes!!! I say shoot the deer mount his head if you really care about him that much and have a few steaks and good times! When I was little my brother and I had to raise cows, pigs, chickens, turkeys, and rabbits. My brother and I even named the animals but when they got big enough we knew they were dinner so we went and did what we had to do. If you wanna make it easier on your conscious think about it this way, like what was said beforehe probably frequents other pieces of property so I doubt he'll make it through thehunting season. So its simple.... either you shoot him and keep him for yourself or your neighbour shoots him.
