I see, I see Danzou just ordering the village leaders to kill the Uchiha clan just for his eyes, so basically, I am not completely sure he had the whole plan with the village leaders, probably teamed with Orochimaru to create Sharingans within Danzou. We would call this some what the greatest criminal diversion in the hidden leaf history. I mean think about it, using the village leaders to allow Danzou to kill the Uchiha clan, just to help out whatever Orochimaru and Danzou cooked up, and besides since Orochimaru was a former high ranked Jonin, he'd know how to convince the village leaders. In the end now the village leaders and Danzou are accused.
