He's brave, loyal, and willing to sacrifice himself to save others. For example, he willingly faces Voldemort in the Forbidden Forest to protect his friends and defeat evil. This shows how much he's grown from feeling burdened by his destiny to fully accepting his role in the fight against darkness. Throughout the series, he learns the importance of friendship, forgiveness, and empathy, which he shows in his relationships with Ron, Hermione, and even his enemies like Snape. Overall, Harry goes from being a young and inexperienced wizard to a wise and caring leader by the end of the series.
