Well, it's a bit difficult to directly recommend a particular 'Let it die a Naruto and Harry Potter fanfic' without more information. However, when you search on fanfic platforms, pay attention to the summaries. If it mentions an interesting crossover concept between the Naruto and Harry Potter universes in relation to the 'let it die' theme, it might be worth checking out. For example, it could be about a character from one universe facing a situation where they have to let something die in the other universe's context.
One emotional moment could be when Sasuke first realizes how close Naruto is to death. His face might show shock and fear, which is a big deal for someone as stoic as Sasuke.

Sasuke's determination serves as a major driving force. It might force him to use his skills and powers in new and creative ways.
