Although this advice is not new information Laertes still gives his father the respect of listening attentively as he is a loyal son.
Hamlet does not want him to be sent to heaven as his father never had the chance to confess before his sudden death and so suffers in purgatory. However, Hamlet becomes angered when he finds Rosencrantz and Guildenstern to be disloyal.
In Hamlet power becomes more important than family, which causes betrayal between two brothers. Before Laertes goes abroad to France, his father Polonius, gives him vain advice that deals mostly with outward appearances and the reflection of his acts on the family.
Most obviously unlike Hamlet, in his impulsiveness and gullible nature, Laertes is too struck with the need to avenge his father after his sudden death. Trust becomes a very invisible in this tragic story. Yet for Rosencrantz and Guildenstern who betray their loyalty to a friend they are executed, for Polonius who is loyal to the King yet goes against ethics he is killed and for Claudius who murders his brother receives his deserved revenge from his nephew.
Through his reflective comparisons of his behavior and characteristics with that of others, Hamlet learns to create his own definition of what it means to be a man.
In highlighting these tensions, Hamlet gives enduring insights into the human condition, allowing this play to transcend its time and remain pertinent to contemporary audiences. This loyalty towards Claudius ensures that Claudius has continued power in Denmark, which in turn causes a downfall.
