Second degree murder is described as an opportunistic action to cause bodily harm or recklessness and disregard pertaining to human life. (I.e. reacting in the heat of the moment in anger)
“Did you hear about the guy who killed another guy at the bar on the tv last night I heard he got charged with 1st degree murder”
“No your thinking of 2nd degree murder he didn’t go out saying I’m going to kill this guy he just lost a game of pool”
