Quite a relatable character that didn't do much wrong for most parts of the series.
Though,
- His relationship to Kakashi was disappointing as kishimoto didn't wrap it up
- his endgame agenda was kinda bizarre and felt constructed to justify the battle VS naruto
- he shouldn't have clapped sakura, he never showed the slightest interest in her. Karin should have been the choice (creating a new uzumaki-ucchiha bloodline) and he could have fully experienced his homo-platonic feelings towards nardo
- he should have kept his sidekicks the water guy and the cursed mark guy, those two went through hell for him
- he should have gotten a semi-official position like danzou instead of being an allied but weird outsider everyone else feels uncomfortable around
