Intent

Foremost among the larger issues at stake in the Eichmann trial was the assumption current in all modern legal systems that intent to do wrong is necessary for the commission of a crime. On nothing, perhaps, has civilized jurisprudence prided itself more than on this taking into account of the subjective factor. Where this intent is absent, where, for whatever reasons, even reasons of moral insanity, the ability to distinguish between right and wrong is impaired, we feel no crime has been commited. We refuse, and consider barbaric, the propositions ‘that a great crime offends nature, so that the very earth cries out for vengeance; that evil violates a natural harmony which only retribution can restore; that a wronged collectivity owes a duty to the moral order to punish the criminal’ (Yosal Rogat). And yet I think it is undeniable that it was precisely on the ground of these long-forgotten propositions that Eichmann was brought to justice to begin with, and that they were, in fact, the supreme justification for the death penalty. Because he had been implicated and had played a central role in an enterprise whose open purpose was to eliminate forever certain ‘races’ from the surface of the earth, he had to be eliminated.
