Claudius continues to talk about the harm of delay, saying “ And hath abatements and delay as many As there are tongues, are hands are accidents; And then this should is like a spendthrift sigh, That hurts by easing.”(-124). This means that if he waits long enough, he probably won’t do anything at all, bringing to question whether he really loves his father. A caesura occurs in the middle of line 124, likely indicating a change in Claudius’ tone, “But to the quick o’th’ ulcer, Hamlet comes back”(-125). He is indicating that Hamlet is the root of his problems and telling Laertes that now was the time to act, or like an ulcer, this pain would burn in his core for some time.
The most obvious place where Hamlet hesitates to kill Claudius comes in Act 3, Scene 3, where Claudius is alone, defenseless, kneeling at prayer, and unaware of Hamlet's presence. Hamlet actually draws his sword and says to himself, "Now might I do it pat, now he is praying; / And now I'll do't" (-4). But characteristically he has second thoughts. He always has trouble making up his mind to take action, although he can act vigorously at critical moments when he doesn't have time to think, as when he kills Polonius, when he boards the pirate ship, when he fights with Laertes at Ophelia's grave site, and when he fiinally does kill Claudius in the last act. Hamlet tells himself that this is not the right moment because Claudius might be in a state of grace and go to heaven, whereas Hamlet's father was sound asleep and Claudius "...took my father grossly, full of bread, / With all his crimes broad blown, as flush as May; / And how his audit stands who knows save heaven?" (-82) Hamlet decides to wait and kill the king "When he is drunk asleep, or in his rage, / Or in th' incestuous pleasure of his bed; / At gaming, a-swearing, or about some act / That has no relish of salvation in't" (-92). This may be only partially an excuse for further procrastination.
