What is the relationship between the scarlet letter and Hester's identity?
For Hester, to remove the scarlet letter would be to acknowledge the power it has in determining who she is. The letter would prove to have successfully restricted her if she were to become a different person in its absence. Hester chooses to continue to wear the letter because she is determined to transform its meaning through her actions and her own self-perception—she wants to be the one who controls its meaning. Society tries to reclaim the letter’s symbolism by deciding that the “A” stands for “Able,” but Hester resists this interpretation. The letter symbolizes her own past deed and her own past decisions, and she is the one who will determine the meaning of those events. Upon her return from Europe at the novel’s end, Hester has gained control over both her personal and her public identities. She has made herself into a symbol of feminine repression and charitable ideals, and she stands as a self-appointed reminder of the evils society can commit.
The scarlet letter represent the various themes of adultery, penance and penitence, and it also brings about the suffering and hardship, the loneliness that she had to endured in the book. It was supposed to signify the gravity of her hideous crimes but it proves to be a powerful sign of identity of her own true self. After her release from prison, she was not allowed to remove the Scarlet letter from her body and resumes her normal life, showing that she stills have to pay for her actions and consequences would still be there. This letter function as a physical reminder the stark truth of Hester's affair with Dimmesdale. Hester determined that her own identity should be controlled by her only rather than let others push and manipulate her around.

This scarlet letter symbolises her entire life, her own experiences and character about who is really her, her inner and outer being. Her past crime is part of her, to denying what she had already done is to deny part of herself, as the sin is what her true self is and will always be.
