'The stupid follow the loud' they always say. When people are scared they don't know who and what to believe.
When the kyuubi attacked the Village of the Hidden Leaf the citizens were scared. Angry at the beast that took away their loved ones in the horrible attack.
When you are desperate and something goes wrong, you want to blame it on something and somtimes rather someone.
The citizens blamed Naruto, because he was the vessel, a jinchuuriki of the Kyuubi no Yoko.
The Third Hokage made a law to protect the boy from the villagers. It worked on the physical part, the boy was protected from any harm of the angry villagers that searched for someone to blame. Sadly on the emotional part the boy was ignored and shunned eith the cold looks of the citizens of the Hidden Leaf.
The boy grew up without a parent's love. He did not know how it was to have a family. Luckily for the boy there were people that did not hated him and did not look at him with cold. They treated him as a normal being with kindness and love.
Because the jinchuuriki was ignored by the village, he pranked people to be noticed. Even if it was negative acknowlegdement, it still was acknowlegdement. That made the boy feel more like he existed.
The boy grew up and became a ninja, as he became stronger to complete his goal to become Hokage. To become acknowlegded by the village and to protect the precious people he had found on his journey.
When his best friend and rival deflected his village his female teammate pleaded him to get him back. He gave her his word, a promise of a life time.
"I won't run away and will never go back on my word! Because that is my Nindo, my ninja way!" He said to her.
Naruto fought to get his best friend back from the hands of the village's traitor, Orochimaru. Sadly he did not succeed, but he never gave up on his friend and became stronger for the sake of his precious people.
When he saved the village from an attack from Akatsuki's leader, Pain, the village finally started to acknowlegde his strenght and he was hailed as a hero of the village. But he always remembered his friend on his journey and the promise he made to his teammate.
After the Fourth Great Ninja War ended he brought back his friend and beated some sense in him, at the cost of his right arm and the left of his best friend. His rival left to travel the world to redeem his sins. Naruto stayed behind and became the village's symbol and hero.
Many years later he took the hat as Seventh Hokage from his sensei, the Rokudaime Hokage. He archieved his dream of acknowlegdement from the villagers, that once shunned him and ignored him.
You shouldn't judge a book by its cover. And learn what the story inside of it is. Learn new things and look into a bright future. So follow you dreams and never give up! That is a lesson of a life time.
