Just that brief description of the crimes the kid committed tells me all we need to know about him. He would have been back in prison for life at some point anyway. He tried to kill somebody. I am glad that evil is locked away for life. There is no mention of what this guy has done in prison to prove any change to his character or disposition.
Shot someone in the course of committing a crime. While the victim is thankfully alive that has nothing to do with the actions of the perp.
