He is the most dangerous man in Konoha.
In his previous life, he established his roots, planned the genocide of the Uchiha clan, transplanted an arm of Sharingan, and walked the wrong path in darkness for forty years. In the end, he was stabbed through the heart by Sasuke and died with everyone hating him.
After returning from rebirth, he holds all the trump cards in his hand: future intelligence, the prototype of the root, and a system that can see other people's "entries".
He can seize power faster. Threats can be eradicated earlier. You can use all your past life experiences to become a more terrifying hero.
But he didn't.
He said at a high-level meeting: "I propose to establish an institution for discovering special talents."
He walked into the Uchiha clan alone and said to Fugaku: "I will discuss a plan."
He brought the child named "A" to the Sandaime and said, "His name is Yamato."
It's not a whitewash. It's a do-over.
A man who knows he will rot in the mud clumsily tries to bloom.
