In Chapter 8 of Frankenstein, Justine's unwarranted confession of guilt and her subsequent execution for the murder of William have a significant impact on Elizabeth and Victor. Justine's confession, which she makes despite knowing that she is innocent, causes Elizabeth great distress and makes her feel guilty for not believing in Justine's innocence. Elizabeth becomes overwhelmed with grief and becomes ill as a result. Victor, meanwhile, is overcome with guilt and regret for not speaking out in defense of Justine and for not revealing the true identity of the murderer. He becomes consumed with anger and a desire for revenge against the real killer, the creature. The events of Chapter 8 serve to deepen the emotional turmoil and conflict that Elizabeth and Victor are already experiencing, and they further highlight the destructive power of secrecy and the importance of speaking out against injustice.
