In Dosteovsky, the perpetrator feels real guilt, confesses, and finds salvation in God. In Woody Allen, the perpetrator gets over his guilt and lives happily ever after, avoiding punishment. In Madoff's case, the perpetrator dies in prison and his family is destroyed.
Of the three, Madoff killed no one. In some sense I think he was a scapegoat for the 2008 financial crisis. That's not to say that he was innocent or that his crimes were insignificant. Only that, due to the timing, he became a convenient target for the public's understandable outrage over the financial crisis.
