I found out when Sasuke was here before. [It's still a sore point.] He told me himself, even as he said that he would kill every Konoha-nin in Luceti no matter what Itachi felt about them. Given at another point in time before I arrived he acted on that same ambition, I think we have reason to be cautious.

[Even now he's trying to keep an objective opinion, and turn back his own emotions about it. His voice is level, keeping every ounce out of it to instead focus on the facts. Kakashi's the higher ranking jounin here. They're screwed if he doesn't do the same.]

What do you think? Sir.
