How does Miller create sympathy for the victims of the witch-hunt in Salem his play The Crucible?

Arthur Miller creates sympathy for the victims of the witch trials through characterization and plot development. The primary victims of the witch trials are John Proctor, Rebecca Nurse, Martha Corey, and Elizabeth Proctor. Miller portrays Rebecca Nurse and Martha Corey as morally-upright, righteous women, who have impeccable reputations and are God-fearing church members. The audience sympathizes with them because they are the last citizens who deserve to be imprisoned or hanged. The fact that Rebecca and Martha maintain their integrity by refusing to offer false confessions contributes to their sympathetic nature.
Miller creates sympathy for John Proctor by revealing his feelings of guilt and shame for committing adultery. Rather than depicting John Proctor as a heartless man, Miller portrays him as a contrite sinner, who experiences remorse for having an affair with Abigail Williams. The fact that John Proctor is willing to ruin his reputation to save his wife and the other falsely accused citizens contributes to his sympathetic nature. By the end of the play, John Proctor and Rebecca Nurse become martyrs in hopes of disbanding the corrupt court and putting an end to the witch trials. Both characters do not deserve to die and the audience sympathizes with them because they sacrifice their lives for a righteous cause. The audience also has sympathy for Elizabeth Proctor, who not only loses her husband but will be forced to raise her children without him.
Another element that contributes to the audience's sympathy for the victims of the Salem witch trials is the wickedness of Abigail Williams, Deputy Governor Danforth, and Judge Hathorne. These characters act as foils to the righteous falsely accused citizens. By emphasizing the malevolent, selfish nature of Williams, Danforth, and Hathorne, the audience has more sympathy for John Proctor, Rebecca Nurse, and Martha Corey.
