I had a friend and mentor who, as legend had it, started young with a bank robbery and did time. He was an example of someone who could be charming and warm as sunshine and like the devil himself, though so far as I know, he didn't kill anyone. He lived in NYC for some years before snow caused the roof of his apartment to cave in on him, and he persisted until he collected from the insurance company and retired on the proceeds. He really had a wide range of goodness and badass. Luckily, I remember his kindness and incisive intelligence.
