Thematic Significance:
* The dangers of inaction: Fortinbras's ambition and willingness to act, contrasted with Hamlet's procrastination and indecision, highlight a major theme of the play. Removing Fortinbras weakens this contrast and diminishes the play's exploration of this important theme.
* The cyclical nature of violence: Fortinbras's final claim to the throne, after a period of bloodshed, underscores the play's message about the destructive nature of revenge and the cyclical nature of violence. Without Fortinbras, this cyclical pattern is less apparent.
* The contrast between different forms of leadership: Fortinbras represents decisive and ambitious leadership, while Hamlet represents contemplation and introspection. This contrast adds depth and complexity to the play's exploration of power and responsibility.
Plot Development:
* Hamlet's motivation: Fortinbras's presence, particularly his willingness to fight for a small patch of land, provides a context for Hamlet's internal conflict. Hamlet, faced with the murder of his father and the usurpation of his throne, questions his own inaction in light of Fortinbras's bold action.
* The play's ending: The play's final scene, with Fortinbras assuming the throne, provides a sense of resolution and an ambiguous perspective on the future. Without Fortinbras, the ending would feel less complete and the audience would be left with a stronger sense of uncertainty.
* The role of fate and free will: Fortinbras's presence raises questions about fate and free will. He represents the forces of fate that shape the course of events, while Hamlet's inaction suggests a sense of agency. This tension is lost without Fortinbras.
Character Development:
* Hamlet's character: Fortinbras acts as a foil to Hamlet, highlighting his inaction and introspection. His presence underscores Hamlet's complexity and internal conflict.
* Claudius's character: Fortinbras's threat to Denmark provides a context for Claudius's anxieties and motivates his actions. Removing Fortinbras weakens the sense of external pressure that Claudius faces.
Overall Impact:
Removing Fortinbras would significantly alter the play's thematic depth, plot development, character development, and overall impact. The play would become less complex and less resonant, losing its exploration of themes like action, responsibility, and fate. The play's ending would also feel less satisfying, leaving a stronger sense of ambiguity and uncertainty.
