How is John Proctor's Dynamic Character changed, in the book The Crucible by Arthur Miller.I was wondering about this question, so i could include...

To me, the major change in John Proctor's character is
that he goes from being a very troubled man who is wracked with guilt to being one who
is serene at the end of the play.

At the start of the play,
Proctor feels so guilty because of the fact that he had this affair with Abigail
Williams.  It haunts him and makes him think very poorly of
himself.

By the end of the play, though, he is able to
regain a positive self-image.  He gets to the point where he feels good enough that he
is willing to die to protect his good name.
