Answer:
Because this monologue's main theme is betrayal.
Step-by-step explanation:
Hamlet wanted the monologue that emphasized the fall of Troy to be recited. This is because this monologue alluded to the Trojan horse, which represented a great betrayal, of someone who was expected to be friends. Hamlet knew that his uncle would see this and if he were really the murderer of King Hamlet, he would be uncomfortable and in a restless spirit.
