Having to go through with the revenge shooting at the end of Red Dead Redemption (when John's son takes over as the central character). I kept trying to shoot the gun out of the guy's hand, stop the cycle of violence. No go. A friend of mine had the same dilemma.

Busting makes me feel good.

That could have been such a beautiful moment if only it didn't look like when Poochie returned to his home planet.
