A dead man and only goodness in the City of God

When I was a grad student at USC years ago, I came across a man lying on his back.  He appeared to have been killed with a shotgun blast to his chest.  We look at the mistake this man made in his life, how he did not learn the lesson of Augustine and of Solomon, and that is to make sure that what we create in life is only good.  This leads us to understand why there appears to be a paradox that a good God would somehow create evil.
