A Troubled Life Cut Short

David Simon eulogizes a drug dealer he got to know in writing his book, The Corner.  He went on to play Brother Mouzone's bodyguard,  Lamar (h/t The Dish):

At fifteen, he was selling drugs on the corners of Fayette Street, but that doesn’t begin to explain who he was.  For the boys of Franklin Square — too many of them at any rate — slinging was little more than an adolescent adventure, an inevitable rite of passage.  And whatever sinister vision you might conjure of a street corner drug trafficker, try to remember that a fifteen-year-old slinger is, well, fifteen years old.
He was funny.  He could step back from himself and mock his own stances — “hard work,” he would say when I would catch him on a drug corner, “hard work being a black man in America.”  And then he would catch my eye and laugh knowingly at his presumption.  His imitations of white-authority voices — social workers, police officers, juvenile masters, teachers, reporters — were never less than pinpoint, playful savagery.  The price of being a white man on Fayette Street and getting to know DeAndre McCullough was to have your from-the-other-America pontifications pulled and scalpeled apart by a manchild with an uncanny ear for hypocrisy and cant.
He could be generous, and loyal. I remember him rushing out before Christmas to spend his corner money on gifts for his brother, nieces and nephews — knowing that his mother wasn’t going to get it done that year. I remember the moments of quiet affection he demonstrated when his mother was at her lowest ebb, telling her gently that she was better than this, that she could rise again. And, too, I remember his stoic, certain forgiveness of his father, who moved wraith-like around those same corners, lost in an addiction he could never defeat.
“I really feel like he’s at peace now,” DeAndre said after Gary’s funeral, explaining that his father was too gentle for the corners, too delicate a soul to be out there along Fayette Street. His father was never going to be what he was. Not ever again.  DeAndre said this with no malice, in a voice that was as loving as any words I ever heard him speak.

That is a story I just can't imagine.  As Simon lists off all the people he got to know who died from the street, I just don't understand how he could do what he did.  It just seems too agonizing to me.
