What is delusional is doubting the word of the creator, who has said many times through numerous characters that Naruto and Sasuke are on the same level. The Sage gave each of them half his power, what more do you need than that?
no the way your interpreting what was said is delusional, you also tend to put your own facts into the manga as if its true when the manga itself does not say that.
for example
"Well here's the fact. Naruto said he was weaker than Sasuke when they met before the war. He said literally in Japanese さすけをやめてできなかったばよ, which means literally Believe me, I was unable to stop Sasuke. Unable, meaning Sasuke was stronger than Naruto. Also, when Ashura defeated Indra, he had an entire army at his back."
here you go on to say naruto admits that he is weak because he could not
stop sasuke.
but as Zawerni kindly stated
"Why do people keep interpreting that as Naruto saying Sasuke is stronger? He's saying he can't beat Sasuke cause if they fight they would both die. Meaning they were equal."
this is the correct way of interpreting it, because you have manga facts of naruto stating the same thing, that they would both die if they were to fight.
but another way of Interpreting it would be that naruto was unable to return sasuke back to the way he was, because naruto sensed that sasuke was not himself. this was the time that he probably sense Indra in sasuke. and you can go back in the manga and notice that at the time karin has stated that sasuke chakra has change.
you should know that naruto is never going to try and kill sasuke, so his mission is not to defeat sasuke but to return him back to the way he was before he got corrupted.
-----------------
and then you stated that ashura had an army backing him up during his fight with indra. if you can go in the manga and find this battle that indra and ashura had, thats right, the manga has not stated anything like that, that is what I consider delusional thinking.
