I mean, Kabuto was influenced by Danzo and Orochimaru the most into becoming what he is. Oro formed Kabuto almost completely, but let us not forget that Danzo was the initiator. Also, I think Oro's ruthless personality and disregard for what is good and what is wrong is thanks to Danzo at least partially. But from where did Danzo pick up that kind of thinking? Is he simply a bad seed, and did all these things because it was his nature or was he formed into becoming evil somehow? Because when we look at Konoha ninjas, in general they don't want to start fights and care for well being of others. Suigetsu even commented that Sasuke is a typical Leaf ninja when Sasuke didn't want to kill anyone which means they are known for being merciful. Especially characters like Hashirama, Hiruzen, Kakashi and others. So I just wonder why was Danzo so fucked up that he influenced many others in a negative way?
