Naruto had a lot of other support systems in his life such as kakashi,shikamaru,the ramen guy etc i think his adventure would end up the same way it does in the show

But the thing is if iruka sensei wouldn't be there, he wouldn't have defeated mizuki and completely pass the shadow clone graduation test, so I think he might have been a bit demotivated.

It would only affect his personality he probably would killl more

And care less about the village but he would still wanna be hokage

And besides iruka wasn’t the only one

Im only highlighting iruka as he was probably the first person to care about him bruh

Iruka's the first ever person to acknowledge Naruto, and the reason why Naruto can use the Shadow Clone Jutsu which he will use 100 times per episode

So he was a factor that helped him feel happy and get acknowledged tho right?
