Regardless of publishing guidelines, the idea of Naruto killing Sasuke for his crimes is patently absurd and goes against everything he stands for.

Also, from the panels on the page before, it looks like Itachi genjutsu's one of Kabuto's snakes so that Kabuto himself will also eat a genjutsu, and disguises himself as one of the crows that he bursts into. Otherwise, the panel of Itachi staring at the snake is entirely pointless.
