Poetic justice refers to a person receiving punishment intimately related to their crime or misdeed. For example, "poetic justice" for an adulterer would be having their spouse be an adulterer.

In Stephen King's "Survivor Type" a doctor with no morals or conscience is shipwrecked on an island. He has a valise of heroin with him. When he breaks his ankle he uses the heroin for an anasthetic and cuts off his own foot, and then eats it. He continues to cut off body parts to fend off starvation, finally cutting off his left hand. The diary he keeps ends there.

It is poetic justice that he has the means and skills to inflict such horrendous suffering upon himself after a lifetime of harming others.

The Inferno portion of Dante's Divine Comedy reads like a compendium of examples of poetic justice.

Poetic Justice is also the name of a 1993 film starring Janet Jackson and Tupac Shakur and directed by John Singleton.
