Broken characters matter as they offer opportunities for character development. Their flaws and traumas drive the plot forward and give the story a meaningful arc. Plus, they make the readers root for them to heal and find their way.
Naruto himself is the most obvious one. His love interests, like Sakura, could be involved. If Sakura were to reject Naruto's feelings harshly, it would break his heart.
