If Kakashi didn't make it and Sakura got hurt, it would be a huge blow to the morale of the village. Konohamaru, who looks up to Naruto and the older generation, would be devastated. He might start training even harder to fill the void left by Kakashi. Shikamaru, being a strategic thinker, would be worried about the long - term implications for the village's security. He would start thinking about how to reorganize the ninja forces. As for Sakura's parents, they would be heartbroken. Her mother might stay by her side constantly, and her father would be looking for ways to avenge Kakashi and find out who was responsible for Sakura's injury.
It could be Orochimaru. He has always been interested in power and experimenting on people. Maybe he saw Kakashi as a threat and Sakura as a potential subject for his experiments. He might have set up a trap to eliminate Kakashi and capture Sakura.
One possible consequence could be a major shift in the relationships within the 'Naruto' world. It would create a huge rift between Naruto, Sasuke, and their respective friends. There would also be a lot of drama regarding family and clan issues, especially considering Hinata's and Sakura's family backgrounds.

Since she has a significant past with Kakashi, her presence in the fanfiction can either be a source of comfort or more pain, depending on how the story is written.
It could also have caused a rift between her and Kakashi. Sakura might start to resent him for not believing in her or giving her the proper training. This could affect the team dynamic.

And in the end, they emerge stronger as a couple. There could also be a plot where an outside force tries to break them apart because they see their combined strength as a threat. But they fight against it and prove that their love is stronger.
It could be due to Sakura's feelings for Sasuke. If she's overly focused on Sasuke and Naruto gets in the way of her plans regarding Sasuke in some way, she might lash out and hurt Naruto without really meaning to cause serious harm.
