Who is the character that openly denounces Parris and has a troubled history with Abigail?

John Proctor is the character who openly denounces Reverend Parris and has a troubled history with Abigail Williams. Proctor’s disdain for Parris emerges from his belief that Parris is more concerned with his reputation and material wealth than with the spiritual welfare of his congregation. This conflict is rooted in Proctor's moral conviction and his own struggles with guilt regarding his past affair with Abigail, which has led to significant tension between them.

Proctor’s character represents a moral center within the play, as he grapples with his own flaws while also confronting the rampant hysteria and injustice occurring in Salem. His public criticism of Parris highlights his growing discontent with the events unfolding in the community and serves as a crucial turning point in his character development. This dynamic sets the stage for Proctor's ultimate fight against the corruption and fear that has overtaken the town, making his denouncement particularly significant in the context of the themes of integrity and reputation within the play.
