He went from being deluded to being a weak leader.
He rambled on about how the clan was corrupt, but then stated that he and Itachi alone could have a bloodless coup. His points were horrible...
a) Itachi could assist him alone... two people are not enough, b) The anbu would assist Itachi... nonsensical, they aren't for Itachi but work for Hiruzen/Danzo, c) The clan is too powerhungry, he can't stop them... then why be a leader?, and d) If they take out the higher ups then all is fine and dandy... no, people would not want an Uchiha Hokage unless it was Itachi, they suspected the clan for the Kyuubi attack, and as such they'd have to take control of all shinobi... how can 2 people subdue 1000s? There is no mass KA, Shisui's eye is deactivated for ten years at this point and Tsukuyomi is not long-term for such a process.
Should have just gone for negotiation and the peaceful route, not vouch for the coup by saying it can be bloodless when they live in a ninja society of assassins and have no genjutsu capable of such a feat anymore.
And if they ever had the ability to control people, then wouldn't it make more sense to use it on a clan of less than 100 people than attempt to change the minds of 1000s in Konoha? Especially when Fugaku himself admitted the clan was power-hungry and corrupt?
