I was playing RDR the other day, allow me to set the scene: I was travelling between Armadillo and Gaptooth Ridge when I hear gunshots. Thinking that someone could be shooting at me I look around for the muzzle flashes, and quickly locate two guys halfway up a rise to the left of the road. Upon closer inspection they're not firing at me, however, but at each other. "Oh cool," thinks I "this is a duel, I'll watch." - which I do. Now, when I get off my horse to loot the body of the eventual loser (opportunist ftw), the winner calmly walks up to MY horse, climbs on it, and begins riding off! "Screw this," thinks I "no bugger nicks my horse!" - so I shoot him in the back of the head. And lose 50 honor! The guy stole MY horse and I lose honor for stopping him!
