Nagato- He is not full of hatred. Despite the destruction of his village and the death of his parent he didn't plot revenge against Konoha (he only destroyed the village to get Naruto). He showed Naruto not to be self-centered.

Itachi- He sacrified himself and his loved ones for the sake of the village and his little brother.

Hashirama- Despite the fact that he lost so many loved one because of the Uchiha he didn't hate them.

Naruto- He started with nothing, never gave up and finished with everything he wanted.

Guy- He put up a good fight against Madara in his greatest form with his own power. Not Hagoromo's power nor Kurama nope... His own.
