How can a character arc affect the overall theme of a story?

A character arc plays a crucial role in shaping the overall theme of a story by reinforcing the central message that the author wishes to convey. As a character undergoes growth, transformation, or decline throughout the narrative, the changes they experience often reflect broader concepts or moral lessons. This journey can highlight themes such as redemption, love, personal growth, or the struggle against adversity, making those themes more tangible and resonant for the reader.

For example, a protagonist who starts off selfish and learns to value community and relationships can exemplify themes of altruism and the importance of empathy. Through this character's evolution, readers can gain deeper insights into the intended message of the story, creating a more impactful reading experience. When a character's development aligns with the themes, it creates a cohesive and unified narrative that enhances the overall significance of the storyline.
