What constrained Louie in Unbroken?

In "Unbroken," Louie Zamperini is constrained by both his traumatic experiences during World War II and his struggles with post-war life. As a bombardier, he endures the harrowing ordeal of being shot down, surviving at sea, and enduring brutal treatment as a POW in Japanese camps. These physical and psychological traumas limit his ability to reintegrate into civilian life, leading to battles with anger and addiction. Ultimately, it is his journey toward forgiveness and healing that helps him break free from these constraints.
