Crucifixion was designed to mock to the max the victim. A good successful crucifixion was when the victim didn't just die, but became a laughing stock. It's difficult for us to imagine this, but crucifixion, as hideous as it was, actually encouraged people to laugh. The Roman death squads were trained professionals. With Jesus, they staged the crucifixion and leveraged the laughter taking the theme from the written notice given them by Pilate to be nailed to the cross above the head of Jesus (Luk 23:38). 'THIS IS THE KING OF THE JEWS.'
