Sighing to himself, Kabuto paused to remember his old master since he doubted that anyone else would be able to mourn him properly. Kimimaro was close, but the boy would only reflect on how "great" the man was and not focus on all his qualities, both good and bad.
The Sanin had been a man of vision, that much had been obvious. He had done what few people in life had attempted to do and focused his entire life on achieving his dream, to learn all jutsu ever created. While the goal itself and the drive to achieve it were both significantly impressive, even the spy would admit that his means of achieving it were a bit lacking in morality… not that he could say that he was an angel himself, but facts were facts. Kidnapping, experimentation, murder, thievery, torture, the man had done it all without batting an eyelash unless he learned something new or interesting. He had done great things in order to achieve his dreams. Many of them could and would be seen by others as insane and criminal towards mankind, but they were great none the less.
The sanin had taught Kabuto many things over the years during his employment, however what the boy seemed to value most was how he learned to manipulate people and plan ahead. How to read others and use what little you knew to bend them to your will. It was something that few truly noted about the man, however those who did see it knew it was one of his best strengths. It was one of the real reasons why he was such a potential contender for the position of the 4th Hokage… it was his charisma. Orochimaru truly understood people… or more specifically people who were yearning for purpose whether they knew it or not, which was why he was able to amass such a large group of shinobi and create his own hidden village within 10 years. Even though his methods were cruel and his mind was crueler, the man appealed to others in a sick sort of way, and it was that simple understanding that enabled him to get so much done in his life. The man truly was a natural born leader regardless of his ideals and views of life.
Then there was of course his power and his genius, but any decent chunin knew that much about the sanin, so Kabuto just skipped over that bit.
