Why can Elizabeth offer John no advice in his last moral agony?

In his last moral agony, Elizabeth is unable to offer John any advice because she recognizes the depth of his internal struggle and the weight of his decisions. She understands that his guilt and dilemma are profoundly personal, rooted in his own values and experiences, making it difficult for her to intervene meaningfully. Additionally, her own feelings of helplessness and the emotional toll of their circumstances leave her at a loss for Words, reinforcing the isolation of his moral conflict. Ultimately, Elizabeth's love for John complicates her ability to provide guidance, as she is deeply affected by his pain.
