By this, I mean mainly Nagato (Danzo's troups helped Hanzo in betraying Yahiko and this deepened Nagato's grudge on Konoha's shinobi), Kabuto (whom Danzo robbed off a real identity and then ordered to dispose of) and Sasuke (whose live was also messed up due of Danzo's orders to Itachi to wipe out their clan). Also, Danzo was chilling around and experimenting with the likes of Orochimaru.

this is not true if he didnt make itatchi do it the vilage would have been destroyed by the uchiha
