Given the situation the pharmacist found him in I would not consider him one of the bad guys. Especially when the other criminal gets released after 5 years at 19 because he was 14 at the time.
The situation of the robbery was fine, but it was the situation of the cold blooded murder that made him a convicted bad guy, it also uncovered his phony injured war hero life, and the lies about being wounded in a shoot out with his bandaged arm and his made up heroic story of a sustained gun fight during the robbery reveals that this guy with his history of mental problems is truly a bad guy.
This was a case of bad guys running into another bad guy, convictions all around, let’s pop a cork.
