Sasuke accepted as Hokage? He can count himself lucky if he is allowed to live in the village without being arrested or executed for his crimes.

Whatever crimes and shady deals Danzou might have commited, he still was the acting Hokage when Sasuke killed him. Also he severely injured several members of the leaf village and tried to kill Naruto and Sakura. Attempted murder might be a less severe crime than actual murder, but it's still a crime.

Then there is also the already mentioned treason, by defecting to Orochimaru and later joining Akatsuki, even if only temporarily, the attempted assasination of Killer Bee and the killing of several Samurai (since they are part of the Alliance, that crime can't just be forgotten by Konoha).
