Well, in many cases, the end of such a fanfiction could involve Sakura vowing revenge if Naruto was killed by an enemy. She could train harder than ever to become strong enough to take on the foe. The other characters would also be deeply affected. Konoha as a whole might experience a period of darkness and reflection. There could be flashbacks to Naruto's life throughout the ending, highlighting his importance. And perhaps there would be a glimmer of hope as the characters start to heal and move forward, but always with Naruto in their hearts.
Often, the story ends with Sakura being forever changed. She might become more determined to protect the village and Naruto's ideals. There could also be a somber tone, with the other characters mourning Naruto's loss for a long time. Sometimes, the story might end with a memorial for Naruto, where all the characters gather to pay their respects.
The story might end with a bittersweet note. Sakura could carry on Naruto's will, like becoming more involved in helping the underprivileged in the village, something Naruto was passionate about. The relationships between the remaining characters would be redefined. For example, Sasuke and Sakura might grow closer as they both deal with the loss of Naruto. There could also be a sense of a new beginning, with the village coming together to honor Naruto's sacrifice and use it as a motivation to create a better future, but still with the underlying sadness that Naruto is no longer there.
