Final answer:
Reverend Hale becomes disillusioned and frustrated with the court by the end of Act Three, ultimately losing faith in its justice and leaving in protest.
Step-by-step explanation:
Reverend Hale's feelings toward the court at the end of Act Three are best summarized as disillusionment and frustration. Initially, he saw the court as a means of upholding justice and rooting out witchcraft in Salem. However, by the end of Act Three, he recognizes the court's actions as unjust and driven by hysteria rather than evidence and rationality. This leads him to denounce the proceedings and leave the court in protest, showing his complete loss of faith in the judicial process as carried out during the Salem witch trials.
