The excerpt explains how utterly useless it is for a man to try and be self righteous when there is pain and suffering being caused. Dimmesdale is in love with Hester, and he finally in his dying breath lets it be known to the townspeople.
Is it possible to attain forgiveness in a Puritan society after committing such a heinous sin? Forgiveness is always a possibility in my eyes, though the puritans see black and white. It is either wrong or right, and Dimmesdale is wrong for having relations with Hester. A punishment suitable for such a sin is already been instituted since the day it happened. Dimemsdale is living with this guilt on his conscience for seven years.
One cannot earn their forgiveness without doing some sort of penance, Dimmesdale's penance I believe was living with pearl. Pearl was a message from God, a message of Anguish. As our narrator tells us "Pearl's errand as a messenger of anguish was all fulfilled"(pg175). It is also possible to say that the penance in which Dimmesdale paid was his life, in which at the end of the book he was supposedly struck down after he admitted to the sin.
Dimmesdale's sermon is a joyous occasion in which he revealed the evil that he has done. This sermon is like a slap on the face to the Puritans by showing their unbeknownst hypocrisy where they shuddered at Hester's scarlet letter yet, Dimmesdale's letter received no recognition. "Thou hast escaped me"(pg 175). In this short yet powerful line Dimmesdale yells to the multitudes that his inner demons have finally escaped him, yet with them I believe they carried away his soul as he then later dies. As the crowd breaks out into a dull awe, they have finally realized what a man is capable of doing. They have realized that human beings need to love and need to be loved. We do not choose who we love, and it is not wrong to have love for more than one person, the puritans I know believe have just realized this in this little epiphany.
