Irony that is inherent in speeches or a situation of a drama and is understood by the audience but not grasped by the characters in the play
In this question, we do not know what point of the story you are referring to. Therefore, we cannot answer in detail. However, we can still look at the character of Reverend Hale and try to understand why he behaves in this way in the play.
Reverend Hale is a pastor who is brought to Salem in order to investigate the witchcraft that seems to be taking place. He is eager to help and excited about this calling, which is what keeps him from seeing the truth. Initially, Hale is too absorbed by his faith and his work to admit that he might be wrong. However, as the play progresses, Hale realizes his mistakes and attempts to change his actions. However, at this point, it is too late to go back, as the trials are no longer in his hands.
