I don't know why everyone is so cold-blooded to the hero's son, perhaps to highlight the hero's early tragedy and bring contrast to his final growth and transformation. Naruto can be said to be a very typical Japanese hero, with a tragic life experience, a simple mind and a single-minded desire to achieve his goals and ideals. Of course, in the process of fulfilling my ideals and goals, I also met friends and people I like. But according to the characteristics of a day, he won't understand his heart so quickly, and he is still a neurotic person who is stupid every day.
Since he is the protagonist, Naruto is very lucky. Although he is simple-minded, he has the courage to go forward and the spirit of blood, so he can also get the guidance of experts. And in the process of growing up, I didn't fall into the mood of self-blame because of a temporary failure. Sasuke is a very typical male image, with a very good background and bearing the hope of the family, but his personality is very indifferent. Without Naruto's influence, maybe Sasuke will resolutely choose a completely different path.
In fact, in addition to these two characters, there is another character I like very much called Kakashi. Although Kakashi is not the protagonist, he is very popular. If everyone doesn't like him very much, they won't tell him lies. Although Kakashi was a mysterious person in his early days, he was very serious, especially when dealing with Sasuke. When Sasuke became a traitor, only Sasuke and Kakashi wanted to believe him and get him back.
