Hmm, i'll take a guess that the Anime team will spin it that Kakashi is gonna be 'fixed' when he gets Naruto and Sasuke, due to Naruto being Minatos kid and Sasuke being Itachis bro. It was always weird how Kakashi let them pass in the end imo.
He completely failed in mentoring Itachi. He couldn't protect Obito nor Rin. His darkness is his path of failure. Of course he will fail every student he gets until they clearly spit out Obito's motto under all the pressure he can put.
