Final answer:
Rostand's tone toward de Guiche in 'Cyrano de Bergerac' shifts from critical to respectful as the character undergoes development, ultimately acknowledging de Guiche's personal growth and moments of honor.
Step-by-step explanation:
In Edmond Rostand's play Cyrano de Bergerac, the tone toward the character of de Guiche evolves over the course of the narrative. Initially, de Guiche is portrayed with a negative tone due to his antagonistic and manipulative traits, embodying the qualities of a traditional villain in the narrative. Rostand's tone is critical, emphasizing de Guiche's scheming nature and his use of power for personal gain. However, as the play progresses, the author's tone shifts to a more nuanced perspective. By the end of the play, Rostand presents de Guiche with a level of respect, acknowledging his transformation and moments of honor, such as when he acknowledges Cyrano's bravery and valiance. This change in tone reflects a development in de Guiche's character, from a figure of scorn to one deserving of a measure of esteem.
Throughout the play, Rostand uses character development and dialogue to illustrate the complex dynamics of personal growth and honor in the face of adversity. De Guiche's evolution is marked by a transition from selfish desires to an appreciation for genuine valor, showing that even characters with negative traits are capable of positive change.
