For some reason, i think Itachi used Mangekyou Sharingan on Kakashi so that Kakashi could copy the technique/ learn how it works, and use it himself for good. By good i mean that Itachi probably has similar motives to the Konoha ninja, but is in a complicated situation.
The situation being Tobi's control over Akatsuki / Itachi. Someone mentioned on the boards that they thought Tobi actually is the one who made Itachi wipe out his clan. And Itachi probably was not supposed to leave Sasuke alive, but did because he is not a villain, and needed someone to surpass him and eliminate Tobi.
And then, Kisame says "From here, it looks like you are crying, Itachi" He seems good.
