Creating a compelling character in a work of literature who can promote extreme political ideas without being noticed requires subtlety and deep characterization. Here are a few ways to help achieve this: 1. Complex character background: Give the character a complex and rich backstory so that readers can understand the motivations behind their thoughts and actions. Make their ideas seem plausible by showing the pain, injustice, or deep personal experiences the character has gone through. 2. Appealing personality: The character should have appealing traits such as wit, humor, courage, or charisma. These traits can attract readers and make them emotionally resonate, making them more receptive to the character's views. 3. Gradual development: Introduce extreme ideas gradually, avoiding direct and sudden indoctrination. Through the development of the plot and the changes in the characters, slowly lead the reader to understand and accept the "reasoning" behind these ideas. 4. Human weaknesses: Show the character's weaknesses and humanity to make them more real and believable. This allows readers to connect with the character emotionally, even though their views may be extreme. 5. **Anti-characters**: Create one or more antagonists to provide different perspectives and opinions. By contrast, the main character’s ideas are emphasized as attractive and logical. At the same time, the antagonist can also be used to balance the story by showing the potential dangers of extreme ideas. 6. **Use metaphors and symbols**: Use metaphors and symbols to convey extreme ideas in a subtle way. Use events, objects, or environments in the story to make readers receive these ideas subconsciously. 7. **Moral dilemmas**: Face characters with complex moral dilemmas in which their extreme positions seem to be logical solutions. This can lead readers to sympathize with the character’s point of view in certain situations. 8. **Reflective ending**: An open or subversive ending forces readers to rethink the impact of the character’s actions and ideas. This can lead to critical thinking about extreme ideas even if they are promoted. Through these methods, the author can create a charismatic character who can spread extreme political ideas inconspicuously while avoiding direct indoctrination. It is important to ensure that the story has multiple levels of interpretation space to guide readers to think deeply.
