I refer to what is called mysterium iniquitatis, meaning, as I see it, that a crime in the final analysis remains inexplicable inasmuch as it cannot be fully traced back to biological, psychological and/or sociological factors. Totally explaining one’s crime would be tantamount to explaining away his or her guilt and to seeing in him or her not a free and responsible human being but a machine to be repaired. Even criminals themselves abhor this treatment and prefer to be held responsible for their deeds. From a convict serving his sentence in an Illinois penitentiary I received a letter in which he deplored that 'the criminal never has a chance to explain himself. He is offered a variety of excuses to choose from. Society is blamed and in many instances the blame is put on the victim.
