1. Murder. The perp knew that when he pulled the trigger it would kill the victim. 2. Depends, did the guy just knock him out with a punch and then walk away, and the victim died? Manslaughter. Is the perp a trained fighter? Probably murder. Did the perp continue to pound the victim to a pulp after the fight was over? Murder. 3. Same as above, doesn't really matter if they knew each other.
It's not premeditated though. I thought murder meant it had to be planned ahead of time. In this case, the man did not plan on killing the guy until he was riled up by the argument. Not a law expert or anything, just trying to understand better.
For point #3, why would previous rapport not matter? That would mean the killing could be premeditated.
