The events of "The Crucible" change Reverend Hale by testing his faith in God. Because he is forced to accept that his beliefs have been manipulated and realizes that he has sent innocents to their deaths, he loses faith in the law and questions his faith in God.
One of the most complex characters in the Arthur Miller play, Reverend Hale undergoes a journey through the play. Starting with the best of intentions, his confidence is shaken as the events unfold, and he becomes completely disillusioned with the justice system and frustrated with the injustice of punishments afflicting the innocents accused of witchcraft. He is forced to question himself and his beliefs when he glimpses real faith in the people he has condemned.
