Explanation:

Elizabeth and John Proctor were two victims of the vindictive Abigail who after having an affair with John decided to accuse Elizabeth as a witch. Elizabeth, as a way to help her husband, ends up lying, accepting the accusation and being arrested and sentenced to death.

John as a way to save his wife lies to the court about Abigail being a prostitute, but he doesn't want to say that he had an affair with her so as not to lose his honor.
