Answer:
In the book “The crucible” by Arthur Miller, John hale changed throughout Act 1 to Act 4. He believed that witchcraft was true but towards the end he started to notice that proctor is telling the truth about him not having nothing to do witchcraft. Hale wanted to find and prosecute witches.
Throughout all of the drama in Salem, Hale changes drastically from a man with intentions to free the world from the clutches of satan to a person who realizes the Salem witch trials were all based on lies and tomfoolery.
Elizabeth's name has been brought up by Abigail as a witch, and Hale wants the Proctors to look like they are religious, upstanding people. He has them recite the Ten Commandments, and John Proctor forgets the one about adultery. He tells them to make sure they go to church from now on and to do whatever they're supposed to as good Puritans. He doesn't want Abigail or any of the others to have a good reason for calling either of them a witch.
At this point, Rev. Hale realizes the witch trials are fake, and he wants to save anymore people from prison or from being hanged. He goes to the Proctors to help them.
