@Integer115 What does that have to do with anything? The comics cover a lot of Zuko and Azula's story, including the childhood that they shared.
Zuko experienced severe childhood trauma that shaped him into who he was, and much of his redemption arc in Avatar: The Last Airbender involved recovering from his trauma so he can grow as a person. Being loved by his father meant everything to Zuko, but his father hated him considering him weak, pathetic, and "lucky to be born." When Ozai put Zuko's worldview into question in The Promise (referring to his telling of the story between Zuko, the turtle, and the hawk), Zuko breaks down as his father lashes out at him. Keep in mind that Zuko lost his mother when he was 11, assaulted and banished by his father when he was 13, and forced to deal with trauma recovery when he was 16. Even before all of this, he grew up with an abusive father and a depressed mother.
All Zuko wanted was love, and he lost his only loving parent when be was a child and was forced to live with a single parent who despised him. When we see him first in Avatar: The Last Airbender his only goal is to capture the Avatar because he thinks it's the only way to earn his father's love. This is because his understanding of "love" has been shattered due to his father's oppressive view of love existing through fear, violence, and intimidation. Zuko doesn't want these things, he hates violence and cruelty, but he also wants to be loved. Ultimately, love allows him to truly redeem himself—love for his uncle, love for humanity.
Zuko isn't a bad person, he's a loving individual who was forced to deal with violence and trauma as a child and a young teenager.
