On this issue, I personally feel that Naruto's life is not bitter.
One: When Naruto was born, four generations under one roof died in Kyubi no Youko, so how did Naruto grow up without friends? Needless to say, it must have been secretly raised by three generations.
Two: Naruto has been living alone since he can remember, so he is at least six or seven years old, so three generations must have helped him since childhood.
Three: after Naruto lives alone, then money is needed for eating, shopping and household items! And Naruto often goes out to eat Lamian Noodles, and he has to pay for noodles! Before Naruto, no one had any source of funds. Who gave the money?
Four: Naruto goes to Ninja School. From the beginning to graduation, the school will charge tuition. Who paid the tuition when Naruto had no source of funds?
The most important thing is that Naruto often plays tricks on others in the village because he has no family ties, hoping to attract everyone's attention. Based on the story background at that time, it is estimated that there are two-thirds ninjas in the village. Do you really think there will be no more pranks in the future? Nobody bothered to find Naruto?
Obviously, there are no three generations behind Naruto, and it is still one thing whether Naruto can grow up completely. I thought three generations really tried their best to take care of Naruto. Naruto's childhood life was very difficult, and the fundamental reason was the invasion of Kyubi no Youko Fox. Naruto's childhood was isolated and rejected by everyone, because everyone thought Naruto was a fox. Three generations once said to Iruka: "Four generations of foxes hope that everyone can regard Naruto as a hero, but adults don't think so. Not only that, but their attitude will also affect children subtly." From this perspective, it is impossible for three generations to regard Naruto as a fox.
So Naruto's life is not bitter, which can't be blamed on three generations. After all, three generations are the highest instructors in the village. You can't let him follow Naruto. There are still many things in Muye village, such as the development of the village and the task arrangement of ninjas, waiting for him to deal with.
