Why is hale telling the accused to lie?

Reverend Hale encourages the accused to lie to save their lives, believing that a false confession is preferable to execution. He feels a moral obligation to protect innocent lives, even if it means compromising his principles. Hale's desperation reflects his growing disillusionment with the court's injustices and the hysteria surrounding the witch trials. Ultimately, he seeks to preserve life, even at the cost of truth.
