Tobirama's reign did not introduce the Academy, that was during Hashirama's reign, though still spear-headed by Tobirama. Tobirama also spied on the Uchiha directly, which contributed to the pro-Madara faction under the likes of Uchiha Setsuna.
Tobirama's cynical views were not the only factor that resulted in Madara's defection. Madara was already leaning that way in relation to the Stone Tablet. It was also not just Tobirama, Tobirama put it up to a public vote, which Madara lost.
Tobirama was not the only reason the Uchiha held their coup. Madara's departure, subsequent attack on the village, Obito's attack on the village, and Obito goading an extremist faction in the Uchiha also contributed to it.
Following Rasa's assacination attempts, Gaara actually fell into line, becoming a more useful asset overall.
Rasa did not really have a choice in not joining the Oto alliance as the Land of Wind was suffering financially due to the Land of Fire, he simply did not predict the betrayal that would have come from it.
Yagura claimed he was "distinguished" as Mizukage when he met Naruto, and his character during that interaction does not seem to match his legacy, so it is likely his negative reputation was solely due to Obito.
The exact circumstances relating to the destruction of Uzshio is unknown, so Hiruzen cannot exactly be blamed for it. The tradition of Uzumaki being hosts dates back to Mito becoming Kurama's first host during Hashirama's reign, so Hiruzen cannot exactly be blamed for it.
The Hyūga themselves agreed with Kumo's demands, as both they and Hiruzen likely knew the alternative was an unwanted war. They did not have much other choice in the matter.
Hiruzen attempted to negotiate with the Uchiha, but failed. He was the only member of the council to attempt this.
Hiruzen had some of the tightest control of the darker side of the politics of his village of any Kage, ever.
Hiruzen only become aware of Itachi's assignment because Itachi met with him after the incident had already occurred to discuss it with him, wherein Hiruzen pledged to ensure Sasuke never wanted, which indeed, he did not, during his life-time.
Hiruzen did not "let" Orochimaru escape, he simply could not bring himself to harm his former student, which he rectified by sacrificing his own life later on to stop him.
Hiruzen did more for Naruto than any other Kage for their host, ever.
Hiruzen did not treat Naruto any worse for being a host, introduced a law into the village to attempt to curb Naruto's mistreatment, gave him free entrance into the Academy, provided him room and board, food, and so on, despite the fact that others viewed Naruto as someone who had killed many of their friends (Hiruzen's included).
Kushina's dying wish was not to take care of Naruto. That was filler.
