Answer:
c. What goes around, comes around.
Step-by-step explanation:
One of the themes covered in "Hamlet" is revenge, that is, in the whole narrative we can understand the concept that the malcasts of an individual should fall on him in the same intensity. In "Hamlet" we see Prince Hamlet organizing himself to kill his father's murderer, who is his own uncle. Hamlet does not believe in the possibility of forgiving his uncle, because for him "what goes around, comes around," that is, his uncle must be signed in the same way that King Hamlet was murdered.
However, this thought is not materialized in such a simple way, because in the search for revenge, Hamlet ends up causing crimes and suffering to many people, also needing to suffer to avenge the acts he committed.
This can lead us to conclude that the search for revenge ends up corrupting a man and making him a promoter of bad situations that will also turn against him, once again confirming the concept that "what goes around, comes around".
