Bomber pilot Yossarian, the protagonist of Joseph Heller's Catch-22, is a complex and conflicted character who struggles to make sense of the absurdity and horrors of war. Despite his fear and desire to escape, Yossarian is trapped in a paradoxical situation known as "Catch-22," which states that anyone who claims to be insane to avoid flying combat missions is, by that very claim, sane and therefore fit to fly.
