In "The Crucible", why does Reverend Hale change his story about witchcraft?This is from Act 3.
Reverend Hale changes his position on the witch trials because he is determined to save John Proctor from execution. He becomes convinced that Abigail Williams is a liar in Act III, after she is asked to respond to the confession of John Proctor to lechery.
Proctor admits to a crime, lechery in the court, a serious crime, this gets Reverend Hale's attention, he considers what would cause a man to confess to such a crime in front of the high court. It must be true, that is the only answer.
Abigail is defiant in her non-response to Danforth, refusing to reply to the question. Hale proclaims that he believes Proctor.
"I believe him! Pointing at Abigail: This girl has always struck me as false"
Hale becomes convinced that the court does not care about the truth, a man has just surrendered himself to the crime of lechery and they do not believe him, they would rather charge him with witchcraft.
Reverend Hale can no longer be a part of this charade that ignores the truth and elevates a liar, Abigail Williams.
