Hale starts out with a vendetta against witches and ends up a broken, cynical man. Hale wins five stars for being the most complex character in the book, if not counting John Proctor here. He starts with the book being good and having only good intentions—even if he has a bit of a chip on his shoulder. During the text and mainly at the end, we see that Hale has become a completely different man than the one we met at the beginning of the play. The tortured Reverend is a great example of the rich, morally ambiguous character for which Miller is famous.
