Protagonists who are dedicated to the fantasy of their ideals becoming reality.

I'm a writer and I've been writing a character by the name of "Byron" and his journey with identity against a political backdrop. He is an extremist but can be perceived as morally objective. However, I fall short. If I could read books with main characters who come off as "strong headed", mysterious and dedicated to their ideas, it would really help. A perfect example is not a book but Johan and Tenma from the anime monster. Rather than a political backdrop, it's crime and thriller. Johan is devoted to countering Tenma's morals, philosophy and ideals and the anime is a sort of tug and pull. The focus however is just the personality of dedication, the setting of politics and the goal of one's idea of a "right".
