Sai is ........ the same place as Kabuto >.>
Sai is not Kabuto, but Danzo is Madara.
Who said that is true? .-.
Plus, danzo's right eye is heavily bandages, and his right is fine, while it's the other way around for madara .-.
Also madara is the mizukage, what the hell would he be doing in konoha unless it's to fight naruto or destroy the village?
Just, so many things that contradict your theory .-.
Danzo may SEEM irrational but he has good intentions for his decisions...
E.G.:
Sending sai out for sasuke;
Sasuke, as danzo said, is becoming much to powerful and a threat to konoha.
Simple.
Whereas, he killed the messenger frog;
Possibly to protect the 9-tails?
I mean seriously, pain obsorbs ninjutsu and physical attacks, kyuubi is basically worthless there...not to mention there are 6 pains rather than 1....
If they were to kill/capture naruto = Game over for konoha.
