Which character’s actions are motivated primarily by a desire for revenge?

The character whose actions are primarily driven by a desire for revenge is Abigail Williams. Throughout "The Crucible," she is portrayed as manipulative and vengeful, particularly in her quest to eliminate Elizabeth Proctor. Abigail had an affair with John Proctor and harbors deep feelings for him, believing that if Elizabeth is out of the way, she can reclaim his affection. Her actions, therefore, are not just a response to the hysteria of the witch trials but are fueled by a personal vendetta against Elizabeth, leading her to accuse Elizabeth of witchcraft. This desire for revenge not only ignites Abigail's actions but also escalates the conflict within the Salem community, illustrating how personal grievances can exacerbate larger societal issues.
