Hamlet doesn't kill Claudius at this point because he believes that Claudius is praying. He says that killing the king NOW would be "hire and salary, not revenge!" He simply cannot send Claudius to heaven, where he would surely go were he killed just after praying and purging his sins. He thinks that would not avenge his father's murder, because Claudius killed Old Hamlet without giving him the opportunity to pray, and therefore, Old Hamlet must spend time in hell. Hamlet thinks killing Claudius when he is fit for heaven would be like paying Claudius for the murder of his father. That simply would not do.
The real irony is that Hamlet does not realize that his revenge could have been complete if he had actually killed the king then and there, because Claudius was not really praying. Oh, sure, he was on his knees, but Claudius says that he knows he cannot be forgiven for the murder unless he truly repents, and repentance would mean giving up his crown and queen. So when Claudius says "My words fly up, my thoughts remain below./ Words without thoughts never to heaven go," he is really admitting that he knows he isn't forgiven. If only Hamlet had known, then Polonius, Ophelia, Rosencrantz and Guildenstern, Leartes, Gertrude and Hamlet all could have survived.
But then, the story wouldn't be a tragedy :-)
Hamlet tells himself that he can't kill the King while he is praying. But the real reason is probably that Hamlet can never make up his mind. Coleridge said that Hamlet "thinks too much." Hamlet sees too many sides to any question. When he does act, it is always on impulse, before he has had a chance to think. For example, he acts very courageously and decisively when his ship bound for England is attacked by pirates. Coleridge's diagnosis of Hamlet's character is probably the best that has ever been attempted. The answer by rishakespeare at this link below gives another perspective on Hamlet's actions. See what he says about "a harsh reality of an immoral world with his idealistic Christian reality."
He needs to "catch" Claudius in the throes of some sin, so that he will die with an unclean soul, thereby sending him to Hell. He has just been absolved of (his brother's) murder because of his prayer.
Hamlet has had many opportunities to kill Claudius. In fact, at this time period, revenge was justified homicide; Hamlet could at any moment of any day have walked up to Claudius and run him through. Unfortunately, this is not in Hamlet's nature. He reveals his hesitation in Act I when he says "O cursed spite, that ever I was born to set it right!" His hesitations and trepidations lead to his circuitous plans - the crazy acts, the denouncement of Ophelia, and the altered play. These get him nowhere, which is right where he wants to be.
Of course, the moment is perfect when Claudius is praying. Luckily, the intelligent Hamlet thinks of yet another excuse to avoid committing an act which is so out of his character. Yes, he is praying, and yes, he will go to heaven. So what? The chance presented itself perfectly. God allows for revenge. Hamlet is only capable of killing Claudius when he, himself, is also dying.
Hamlet doesn't kill Claudius at that moment because he thinks that Claudius is praying. Hamlet says that killing Claudius now would, "send [this same villain] To heaven” instead of Hell where he belongs. Hamlet vows to kill Cladius as Cladius had killed his father, and not send him to heaven.
At that moment when he sees Claudius he finally has the chance to kill him. After stretching the task ages and ages, finally Claudius is in front of him, but he does not want to kill him because he believes he is asking God for forgiveness. He wants Claudius to go to hell and if he kills him while he is praying, then Claudius will be sent to heaven. That is why he waited to kill Claudius.
Hamlet sees Claudius praying and assumes that Claudius is praying for forgiveness and if he kills Claudius then and there he will go to Heaven.
He did not want King Claudius to go to heaven.
An Oedipul analysis woul have thought that Hamlet cannot kill Claudius because Claudius is in the position Hamlet wants to be in. In a sense they are quite similar.
Oedipul Complex - The idea that a male wants to kill his father and marry his mother.
Hamlet decided agianst killing claudius because he felt that it will grant him a chance to gain heaven, due to the fact that he was praying at that time. he believed that his prayers would have meant a free passgae to the Kingdom despite his crime. it is also obvious that in a prayer mood, one may not know that thoughts or prayers of the penitent, hence, it could be that he was asking for forgiveness at that instance. From another perspective, the weakness of Hamlet as a procastinator may be the reaason behind the postponement.
Hamlet wanted to avenge his father,s murder but througout the play we find him in a fix as what to do or what not to do, to be or not to be that is the question, on one hand, he has to avenge his fater ,s murder at the same time he is also a man who wants to follow and do everything as per moral integrity, that is why he can not take the action of murder so easily , he goes on analyzing whether should he do or not, meanwhile he also saw his uncle doing prayer, so he thought that if now takes revenege from him, his uncle will reach heaven and that he does not wish for him.
Actually shakespeare here depicts a universal human being who is in a fix between right and wrong before taking any action
Hamlet does not kill Claudius because he is praying. According to the catholic beliefs (which are referred to regularly in the play) Claudius may have been forgiven his sins due to his repentance. And therefore have gone to heaven.
Hamlet's father was murdered directly after his midday meal - without chance for repentance - and is therefore condemned to purgatory, where he will be "purged" of his sins. Knowing what his father has to face, Hamlet wants to cause the same suffering to Claudius. For this reason he cannot avenge his father while claudius appears to be in prayer.
Ironically, Claudius is not truly in prayer, but poor Hamlet has no way of knowing this.
Gentle Hamlet is conflicted throughout most of this play - should he avenge the death of his father or be a coward and let it go? When he comes upon his traitorous, incestuous uncle in what appears to be a posture of prayer, Hamlet makes what could be construed as an excuse as to why he does not kill him: Claudius is kneeling in the castle's chapel in what Hamlet believes to be parayer. For this execuiton to be truly revengeful in Hamlet's eyes, Claudius must be caught in an act of sin, with the end result eternal damnation. His conflict is further fueled by the suspicion in Act I that the ghost of his father may have, in reality, been a demon tempting Hamlet to sin by committing murder himself. Poor Hamlet is a hot mess trying to decide who he really is and who is directing his path. He decides to wait for a more opportune time to kill his uncle.
Hamet doesn't kill Claudius because he is praying for forgiveness and it is belived that in the act of praying if killed one is innocent and forgiven of all sin. meaning that if hamlet had killed claudius he would have gone to heven.
Hamlet does not kill Claudius when he’s in the chapel as Claudius was praying to the god. Hamlet is armed; he draws out his sword and is in the position and mood to kill King Claudius, but does not kill him, as of the thought that if he kills Claudius while he’s praying, confessing his sins, Claudius will have the chance to go to heaven. He wants Claudius to end up in Hell and controls his emotions. He decides that he will kill King Claudius when he’s involved in some indecent activity, like “drunk asleep, or in his rage, or in the incestuous pleasure of his bed, or at a game swearing”.
In this scene the action reaches a crisis. Hamlet sees the king at prayer. He gets a golden opportunity to avenge his father`s death.But he thinks that if he kills the murderer at his prayer, his soul would go to heaven, and abstain from action.He thus misses a golden opportunity,for he does not want a wicked soul to enjoy the pleasure of heaven. Wishing for some other occasion when the king is indulging in some evil deed,Hamlet leaves the place.So evil is evil.As it is said: Virtue is rewarded and vice is punished.What he does in prayer? May be he is crying for mercy. Mercy comes with repentance,but in him we dont find any repentance.
I agree with all of the above. To send Claudius to heaven when his father is obliged to suffer in purgutory because his death was without absolution would indeed be unfair though as someone else said Polonious was only trying to pray for he could not manage it so it is an irony that Hamlet could have achieved his declared ends by killing him there and then.
However throughout the play we meet the thoughtful, intellectual Hamlet who struggles endlessly with the decision to kill his uncle. He has been stirred up - at the witching time - after he has been verbally fencing with Polonius and Rosencrantz and Guild. to confront his mother when unplanned he passes through the chamber where Claudius prays and noticing him on his knees says -'now may I do it, pat..." . He certainly hadn't worked himself up for that particular deed in advance, his fury is elsewhere. This is a extremely emotional young man, emotions high and raw with his sense of injustice and need to revenge so he would rush in drawing his dagger seeing his opportunity but his natural inclination to stop and think has been his constant companion so on the very brink he hesitates, thinking of yet another reason to delay the deed.
Hamlet could have easily killed him but His chicken was ready and by the time he kills and cleans up Claudius, his chiken would have been done for... so he decided to kill him later when hes not budy :)
'Praying' of his uncle in this case is just an excuse for Hamlet to escape away from attempting to kill Claudius. Temperamentally he suffers from the flaw of 'indecision' and 'uncertainty' which renders him impotent for any such action. Therefore, the Prince of Denmark takes a temporary refugee in the religious dictates or the morality/immorality of killing a fellow human at the time of prayer only to hide his helplessness and inadequacy (i.e. indecision/uncertainty/impotency) and delays his vowed revenge. This delay in avenging his father's death later brings his own downfall in the fencing match with Claudius which points out to this tragic flaw in the noble character of Hamlet.
