I could not had made it more clear that the Cleric of Death had a grudge against the barbarian and the rest of the original party members. This all happened over the course of a few weeks in-game. Yet the only thing he sees is that I was just gunning for his head and acted smug online about I tried to kill him with an assassin but he totally foiled me with his awesome.
Sorry to say it, but it just sounds like a problem player to me. It's difficult that he is your friend, so I'm not sure how to advise handling it without knowing the dynamic of your relationship.
I know I have friends that I just can't do certain activities with because they lead to conflict. You may need to let him know you won't be DMing for him in the future because his attitude with the game is affecting your friendship. Start a game up in the future with the other players who don't seem to have attitude problems.
