Ask AI: In act 5 scene 2 of hamlet. What figure of speech is used in these lines? How does the comparison serve to justify Hamlet’s actions?

In Act 5, Scene 2 of "Hamlet," one of the most notable figures of speech is the metaphor used by Hamlet when he compares Rosencrantz and Guildenstern to "adders fanged" (venomous snakes with fangs exposed). He says: "There is a special providence in the fall of a sparrow. If it be now, 'tis not to come; if it be not to come, it will be now; if it be not now, yet it will come: the readiness is all: since no man has aught of what he leaves, what is't to leave betimes? Let be." This metaphor serves to justify Hamlet's actions by illustrating Rosencrantz and Guildenstern as treacherous and deceitful operators, akin to poisonous snakes ready to strike. By likening them to dangerous creatures, Hamlet rationalizes his decision to dispose of them as a necessary act of self-defense and moral justice. Furthermore, Hamlet’s philosophical reflection on fate and providence in the broader context of these lines suggests that he believes in a divine order or destiny that governs life and death. This sense of inevitability underlines his acceptance of his fate and the events that have transpired, thereby reinforcing his actions as not just justified, but also pre-ordained or beyond his control. The metaphors and reflections combined help to articulate Hamlet's internal reasoning and moral position, providing a deeper justification for his actions to the audience.
