If this man were not an evil-doer (ei mh hn outov kakon poiwn). Condition (negative) of second class (periphrastic imperfect indicative), assumed to be untrue, with the usual apodosis (an and aorist indicative, first aorist plural with k). This is a pious pose of infallibility not in the Synoptics. They then proceeded to make the charges (Luke 23:2) as indeed John implies (John 18:31, John 18:33). Some MSS. here read kakopoiov (malefactor) as in I Peter 2:12, I Peter 2:14, with which compare Luke's kakourgov ( 23:32 f.; so also II Timothy 2:9), both meaning evil-doer. Here the periphrastic present participle poiwn with kakon emphasizes the idea that Jesus was a habitual evil-doer (Abbott). It was an insolent reply to Pilate (Bernard).
