Final answer:
Victor remains silent about the true murderer due to a mix of guilt, fear, and internal conflict, resulting in the tragic unraveling of the narrative in Mary Shelley's 'Frankenstein'.
Step-by-step explanation:
Victor Frankenstein's reluctance to speak the truth about the murderer in Mary Shelley's Frankenstein is rooted in the complexity of his emotions and actions towards his creation.
His silence can possibly be explained by his own sense of guilt, fear of not being believed, and the horror of having to admit his part in the creation of a being that became a murderer.
Moreover, by not speaking the truth, Victor is attempting to deal with the internal conflict and the consequences of his own actions, which contrasts his initial ambition with the grim realities of his achievements.
His failure to inform others about the true nature of the murderer intensifies the tragic elements of the story, as his own secrets and guilt incubate the disaster that unfolds.
Victor's character is a study of ambition, responsibility, and the consequences of playing god, paralleling themes in other Gothic novels that explore the monsters lurking within society.
