The general concept is that Root doesn't do team building because they simply know their job and do it. Their job isn't about trust, dedication, and teamwork. Danzo saw things like emotional entanglement as being in the way of the mission, which makes sense give that flashback where he was too afraid to offer his life for the mission.

In short, its the traditional issue where you put a self-disciplined, assassin lone wolf and put him into a functional team group. They don't blend well. Sai cared very little for Naruto's feelings and his wants, and taunted him for his lack of maturity, when in reality it was his lack of functional team work that made the issue so difficult.
