Fearing that Hamlet is a threat to his life and throne, the King summons Rosencrantz and Guildenstern and instructs them to hurry and take Hamlet to England. The men agree, acknowledging that any threat to Claudius is a threat to the people of Denmark, so they will keep Denmark safe by removing Hamlet from its shores. They leave, and Polonius enters to inform the King that Hamlet is on his way to Gertrude and that Polonius plans to hide there and eavesdrop on the conversation. Promising to report back to Claudius before Claudius retires to bed, Polonius leaves.
Claudius then prays at his private altar, although he says his sin is so great that it renders him incapable of praying. He admits before God that he has committed the "primal eldest curse" by carrying out his "brother's murder." He admits that his contrition is unforgivable since he is unwilling to give up the spoils of his ill-won battles. He begs instead that some divine assistance might bow his knees and soften his heart so that he can ask for forgiveness.
Hamlet enters and sees Claudius in prayer. He recognizes his perfect opportunity to kill Claudius, but stops himself. He remembers that Claudius killed King Hamlet without allowing him any opportunity to make amends for his sins, and that King Hamlet now languishes in purgatory awaiting entry to heaven. Believing that Claudius is praying for forgiveness, Hamlet knows that by killing Claudius now, he would send the King straight to heaven. Claudius would escape the eternal punishment that is his due.
