Although he is a libertine and a sinner by his contextual Puritan standards, he is easily recognizable to 1950s audiences in a Christianized America. He is an ordinary man who has made mistakes, but is intrinsically good and is morally redeemed at the end of the play. An injustice is done to John Proctor (his wife's accusation of practicing witchcraft and his eventual signing of the legal document that he was convicted of witchcraft). Proctor is driven through much of the play by the desire to save Elizabeth, although these actions are not always entirely ethical or compassionate, as Mary Warren recounts: “'I will kill you,' says he, 'if my wife is hanged! ' “In the style of a tragedy, Act 4 finds Proctor grieving over his metaphorically irreparable morality; “My honesty is broke, Elizabeth; I'm not a good man." Although Elizabeth assures him that there is still good in him, Proctor sacrifices himself by signing the legal document and being sentenced to hang. Although Proctor was not a righteous man, it is his self-sacrifice for a crime he did not commit that echoes (through biblical allusion) the death of Jesus and ensures John Proctor's eventual death.
