In Act 3 of The Crucible Reverend Hale serves as a liaison between the courts (Danforth, Parris, and Hathorne) and the accused (Proctor, Corey, and Nurse). While Hale previously has been on the side of the courts, Hale now believes the trials are bigger than previously believed. He begs Danforth to send Proctor home for a lawyer, but Danforth refuses to allow it.
Once Danforth tests Elizabeth about John's adultery, Hale again pleads with the court to understand. Yes, Elizabeth lied, but "it was a a natural lie to tell." hale realizes that Elizabeth lies to save her husband's good name. As Reverend Hale transforms his character, Act III is pivotal is showing him the ugly truth behind the trials. When he "quits the court" at the end of the act, it is because he believes that the courts are so biased that they cannot and will not listen to the truth.
