There are so many violence in anime .
Zabuza death, jiraya death , pain attacking konoha and even obito face get crashed.
There are so many violence in series and it will take me all day to mention to u the violence scenes in the series
You can't hold the author accountable for someone elses actions. There's violence in almost everything, it is up to us to know the difference between right and wrong.
Kishi never condoned suicide in his manga, but rather sacrifice.....two completely different things. Naruto is about achieving peace, and peace only has value once the viewer understands violence.
Naruto isn't even that violent compared to other anime.
Like with every artist and storyteller, their purpose is to entertain or to teach.....not for others to kill themselves
