He might be shocked. In the fanfic, if he sees things like his friends' future achievements or the new threats that emerge, it would surely startle him. For example, if he discovers that one of his friends has a family of their own and has become a great leader in the village, he would be proud but also a bit surprised at how much has changed.
With his usual determination. Naruto has always been one to face difficulties head - on. So, even if he's shocked by what he sees in the fanfic's future, he'll likely try to find solutions immediately.
The original Naruto has a strong moral compass. However, in 'evil naruto fanfic', this moral code is often broken. He could be involved in things like assassinations or betraying his comrades, which is completely opposite to his character in the official story. This change can lead to a much darker and more unpredictable plot.
Naruto might become more introspective. Dealing with the extreme evil from The Evil Within, he'd start to question his own inner darkness. He could learn to better control his negative emotions as he faces the nightmarish situations. His understanding of the power of the mind would also grow, which could lead to new jutsu related to mental manipulation or defense.
πI recommend the following two novels to you. I hope you like them:
1. "The Legend of Muye Taoist" was about a legendary Taoist who came to the Naruto World with the skills of a legendary Taoist. Legend had it that there was a person who brought a dog with him. This novel was similar to Naruto: The Descent of the Evil Emperor. They were both Naruto Doujinshi novels.
2. In "The Beginning of Naruto: Angering Uchiha Weasel," the protagonist was a super Naruto anime fan who transmigrated to the Naruto world and accidentally awakened the god-level punching system. From then on, he began a new journey to dominate Naruto. This novel could also satisfy the love of Naruto Doujin novels.

I'm not sure if it's popular. There are so many different types of fanfictions out there that it's hard to gauge the popularity of just this one. It might be popular among a small group of fans who are interested in exploring darker versions of Naruto and Hinata's relationship.
I'm not sure specifically as there could be many different takes on it. But generally, it might involve Naruto having an 'evil' side while also being involved in gaming - like using gaming - like skills or concepts in his ninja world. Maybe he uses game - like leveling up to gain power in a more devious way than in the original story.
πI recommend the following novels to you:
"Practicing Star Absorption Technique in Naruto."
"Muye Shinbutsu: Starting from the Revenge Team."
"Guarding the Ninja Realm for 100 Years since the Warring States Period."
[Muye's Free Life]
Warlock Invasion of Naruto
"Lord Ban's Dimensional Life Simulation System"
