Final answer:
At the end of Act 3 in 'The Crucible', Reverend Hale denounces the witch trials and quits the court, indicating his disapproval and disillusionment with the proceedings.
Step-by-step explanation:
In Act 3 of The Crucible, Reverend John Hale's disillusionment with the witch trials reaches a climax. Disheartened and frustrated with the court's procedures, Hale denounces the proceedings and quits the court. After witnessing the hysteria and realizing the judicial process is deeply flawed, likely executing innocent people, Hale decides that he can no longer be part of such injustice. Although he doesn't physically leave the town at this point, his departure from the court symbolizes his shift away from the theocratic and unjust actions of Parris and Danforth (the antagonists), marking a pivotal change in his character from that of an ardent witch hunter to one of skepticism about the legitimacy of the trials.
