1st yes pervy sage, neji and asuma died. you gotta accept that now nothings gonna change if you rage. you just gonna think about what episode, who is the enemy and how did they die
2nd no Sasuke didn't die in boruto not even in the Manga.
or atleast at the latest Manga.
3rd don't check comments I came from episode 90 I want to watch the fillers to so I came back. don't check the comments because they have spoilers.
