Some fans might be drawn to dead Naruto fanfiction because it offers a different perspective. It can make them appreciate Naruto's character more by seeing how his death impacts the story. It also allows for exploring darker themes and different character developments that wouldn't occur in the main canon where Naruto survives.
Dead Naruto fanfiction can have a polarizing effect on the fandom. On one hand, it can create a lot of interesting discussions. Fans can debate about how the story should have continued after Naruto's death, what the implications are for the other characters, and how it changes the overall Naruto universe. On the other hand, some fans who are more attached to the positive, hopeful side of the Naruto story might not like these types of fanfictions as they go against the main theme of Naruto's journey of growth and success.
