What sins does Elizabeth thinks she has committed?

In Arthur Miller's "The Crucible," Elizabeth Proctor believes she has sinned by being a flawed wife and for her coldness towards her husband, John Proctor. She feels guilt over her inability to forgive him fully for his infidelity and struggles with feelings of inadequacy. Her sense of sin is compounded by the societal pressures and moral expectations of the Puritan community in which she lives. This internal conflict reflects the broader themes of guilt and morality in the play.
