What enable Hamlet to see Rosencrantz and motives?

Hamlet's keen wit and understanding of human nature enable him to perceive Rosencrantz and Guildenstern's true motives quickly. He suspects their friendship's inauthenticity and quickly recognizes that they have been sent by Claudius to spy on him. Hamlet observes the subtle nuances of their speech, body language, and behaviors, picking up on hints that suggest their duplicity.

Throughout the play, Hamlet expresses his disdain for Rosencrantz and Guildenstern, referring to them as "sponges," emphasizing their tendency to absorb and pass on information for Claudius. He even confronts them directly, demanding to know why they have come. While they attempt to deceive Hamlet, he remains perceptive and sees through their charade.

Hamlet's capacity for introspection and his acute awareness of human flaws grant him the insight to uncover Rosencrantz and Guildenstern's disloyal intentions. Their inability to match his intellectual astuteness makes them vulnerable to his scrutiny. By contrast, Hamlet maintains his complexity and depth, demonstrating his superiority in terms of intelligence and wisdom.
