Itachi

Regarding Itachi: he's a product of the system built by the Second Hokage. Tobirama is one of my favorite characters, extremely competent and no weaker than his brother if he'd decided to fully utilize his resources. But by supporting the First Hokage's idea, he lost everything just like Madara. Moreover, the Senju were exhausted and died even before the Uchiha. In my eyes, Itachi isn't even a traitorous bastard who killed his family and his beloved. He's an ordinary man, who, when asked "my dog ​​or someone else's child," would select "my dog" and then enroll his daughter in gymnastics, where she'll be brutally abused for the sake of a spectacle that even society won't gain anything meaningful from.
