Actually, this is just one of my hot takes, which I've noticed no one ever seems to... well, take into consideration. Honestly, it came to mind while reading fanfiction, specifically, dark!Naruto fanfics. I've always loved this idea in general. Why, because I thought Naruto had to get revenge? No, actually. Why, because I like character study? Yes, that's literally my reason. I see that many have a specific vision of Naruto's character that I... just don't think I share or totally agree with. Obviously, everyone knows that Naruto is who he is... thanks to Iruka. So, the question arises... what would it be like if it weren't for his support, how would Naruto be?
Many fans see Naruto as more serious, quiet, cynical... a bit more like Gaara, for example. And I understand why they think that... but at the same time, Naruto isn't Gaara, you know? It's true that in the manga Naruto often says that, if it weren't for Iruka, he would have become that way (more cold, that wants revenge, ecc.), but I've always interpreted it more as Naruto's empathy towards others, in understanding how they got to that point, WHY they got to that point.
Of course, it's normal to think that if someone is alone, they automatically become colder and quieter, etc., but not everyone reacts the same way, you know? For example, take Naruto in the early begging of the first chapter. Sure, he has Iruka as support, BUT not really yet. The whole mess with Mizuki hasn't happened yet, Iruka hasn't saved him yet, Naruto hasn't discovered the fox inside him yet, and Iruka... hasn't defended him yet (telling Mizuki that Naruto is not a monster ect.). So, the point I was getting at is that, Naruto was alone up until that point, and we all know that his coping method was to attract negative attention by being loud and making a mess, and wanting to become homage to be accepted by the village. In short, totally the opposite of a cold and cynical person.
Actually, if I had to think of a dark Naruto, it would be more of a version of him that's like, really repressed, hasn't matured, is unable to develop actual bonds that don't implicate total sacrifice and many more attachment issues that, yes, he does have in canon... but like, worse. Idk, tho, maybe I'm misinterpreting it?? The thing is, I'm not saying that he wouldn't want revenge, but he seems totally like the guy who would repress it so bad (like his anger towards the village) and would keep sacrificing himself in the hopes to being accepted and not seen as a monster anymore until he can't take it anymore.
