Final answer:
Laertes and Fortinbras serve as foils for Hamlet, highlighting his indecisiveness and inaction. Their behavior relates to the themes of advice and duty, action versus inaction, and sanity versus madness.
Step-by-step explanation:
Laertes and Fortinbras are both foils for Hamlet, meaning they highlight certain traits in Hamlet's character through comparison and contrast. Laertes is a young man seeking revenge for his father's death, much like Hamlet, but he is more impulsive and quick to take action. Fortinbras, on the other hand, is a prince who wants to reclaim his land through military strength, demonstrating a direct and decisive approach to achieving his goals.
Laertes' behavior relates to the themes of advice and duty and action versus inaction. He seeks advice from his father and follows his duty to avenge his death, showing a sense of honor and duty. His behavior contrasts with Hamlet's indecisiveness and inaction.
Fortinbras' behavior relates to the themes of advice and duty and action versus inaction as well. He receives advice from his uncle and takes decisive action to reclaim his land, demonstrating a strong sense of duty. His behavior highlights Hamlet's hesitation and lack of action.
In terms of sanity versus madness, Laertes and Fortinbras both appear more sane and focused in their pursuit of revenge, while Hamlet's perceived madness adds complexity to his character.
