"Punishment usually serves no noble purpose" is something that Martin Nowak has argued with members of the press, at a time when Mr. Epstein was scared that he could be re-indicted on the felony sex-trafficking charges, which in his case given the egregiousness of his misconduct would have almost certainly led to serving a life sentence in federal prison.
From your comment, I'm now starting to wonder if the word "noble" was accidentally misspelled in the Science magazine interview quoted above.
