Sounds to me that he isn't into hunting but killing and him killing is all that matters. That's not a hunting friend. I've had one like that, actually came as a friend of a friend. He always got mad if someone else shot a deer, would grab the first decent spot when we scouted, then get mad if we later found a better spot and he already had hung his stand. We actually discussed going on an outfitted WT hunt once, with bows, the place had a 125 pt minimum. End result was we didn't go, one reason was he stated he was shooting whatever he wanted an would gladly pay the fine.
I actually bowed out since he was related to my friend (who WAS a good hunting partner), and figured friend vs family is not a good decision to put him in.
