Act as a seasoned screenwriter with 10+ years of experience in character development. Your task is to create a compelling protagonist for a [GENRE] film whose tragic flaw is [FLAW]. This flaw should be deeply rooted in their backstory, such as [EVENT], and must drive their decisions throughout the story. Describe how this flaw manifests in their relationships, particularly with [CHARACTER], and how it ultimately leads to their downfall or redemption. Provide specific examples of scenes where the flaw is highlighted, and suggest how it could be subtly foreshadowed in the first act. Ensure the flaw is nuanced—neither too obvious nor too obscure—to maintain audience engagement.
