this is what i think
okey guise this is what i think, i think danzou is not bad he is just looking out for the well being of konoha as he did trying to kill sasuke, now we now 2 things he's good and is something that involves the Uchiha. If what tobi says is correct of danzou ordering/knowing Itachi to kill all of the Uchiha clan Itachi might of been part of anbu roots, which meant that danzou knows about Madara, and his plans to control the ninetail fox but he probably needs to perfect his mangekyoru sharingan to do so, therefore needs another sharingan user only ones left Sasuke, Itachi was powerful enough to not lose against Madara mos probably the reason why he was the one ordered to kill all of Uchiha to prevent another disaster, now sasuke is equiped with Itach's jutsu and was able to fight hand to hand against Itachi so he is good for fending against madara but i believe Madara figured that out and now is just planing on corrupting sasuke in believing that Konha is responsible for the death of his family and clan so they can both attack it manipulating naruto. But for their suprise i believe Naruto has gotten control over the nine tail fox....but what i will like to know is what is going on on the other end with the Rinnegan and the death of Jiraya-sama
