Final answer:
John says to let Abigail charge him with lechery in Arthur Miller's 'The Crucible' to reveal the truth and expose her motivations for accusing others of witchcraft.
Step-by-step explanation:
John says to let Abigail charge him with lechery to expose the truth of their affair, thus revealing her motivations for accusing his wife, Elizabeth Proctor, and others of witchcraft in order to remove them and take Elizabeth's place. This occurs in Arthur Miller's play The Crucible, which dramatizes events from the Salem witch trials. In a society deeply concerned with sin and reputation, an accusation of lechery, or excessive sexual desire, would seriously damage John's standing but he chooses this path as a desperate measure to save his wife and undermine Abigail's credibility.
