Maybe. But i think a sharingan can do it only when Kurama is out (not sealed inside someone).then so can kakashi
of course he was, he was the only one who cared about the village inside of his family, and clan.it's not just having the mangekyo sharingan or the eternal mangekyo sharingan. I don't think Itachi would ever even care to. I mean, we should all admit that Madara was powerhungry and Itachi wasn't. In the end, Itachi never even needed power because he already had it and unlocked it himself. Without a doubt, he was the least (if having any) greedy Uchiha member. Now that I think about it, Itachi was completely different from the rest of his family.
