Troy: "When I found you and Cory and a halfway decent job...I was safe....I wasn't going back to the penitentiary. I wasn't gonna lay in the streets with a bottle of wine. I was safe. I had a family." (2.1.116)
Here we see that Troy truly values his family. He sees it as the thing that saved him from a sad life of jail, homelessness, and alcoholism. You could say that the real tragedy in the play isn't Troy's eventual death, but the disintegration of his family.
