Cargas opens with the idea that he prays for mercy rather than justice. He acknowledges that forgiveness can be misunderstood—that it can place one human being above another—but that it remains a virtue.
Cargas puts forward the unique idea that forgiveness can be dangerous because it puts the victim in a position of power over the perpetrator, though he dismisses this concern quickly.
Cargas addresses a reference in Christian Scripture to “unforgivable sin,” interpretations of which vary. He argues, however, that if there is an unforgivable sin, certainly the Nazis have committed it. He himself would not be able to forgive Karl, as Simon could not.
In seeming contradiction with his first statement, Cargas works out his thoughts in his response and comes to the conclusion that even Christianity cannot allow for this magnitude of sin.
