Itachi wasnt the type to kill ppl as he was a pacifist thats why he was a genjutsu specialist, and naruto is the hero hes not going to kill anyone thats what kakashi and sasuke are for.
Naruto killed Kakuzu.
I can't think of anyone Itachi killed that wasn't fodder.
NAruto killed all 6 pains .. various edo tensai including 3rd Raikage ,,,
And Itachi , He is A Pure Killer(UChiha Is not a fodder Clan...)..
