Irrelevant if Sakura helped Sarada or not, no Uchiha has ever needed their parents' help, which you brought up by saying that Sarada being a boy wouldn't bring Sasuke back.
Anyway, the idea that one charcter would bring up the reputation of a second place clan is illogical.
What does that have to do with anything?
Because they were already getting killed off in one generation: Hashirama's. If the Senju were always stronger, then that would have lasted thousands of years and the Uchiha would have been extinct long before they reached Hashimadz generation.
Your argument failed the moment you said an Uchiha has never needed their parents help, especially when Sarada laughs at the argument itself.
What's worse is that for some reason your trying to say an Uchiha doesn't need their parent to grow stronger, but apparently the only Uchiha who didn't have their parent up until a certain time was Sasuke. How else do you think Clan techniques are passed down? Oh, I'm sorry, did you not see where Fugaku was training Sasuke in Katon release.
You know the same technique he uses till this day :lol
Anyway, the retardation notion that a clan member cannot showcase what the clan is worth is retarded. Especially when Kishimoto had the Hyuuga state they were /currently/ the most powerful clan in Konohagakure. Hope you know neither Naruto's family (Uzumaki) or Sasuke's family (Uchiha), are clan's themselves. If you want to know what a Clan is, google it.
Wait I'll do it for you:
clan
klan/Submit
noun
a group of close-knit and interrelated families (especially associated with families in the Scottish Highlands).
Re-read your last post and you'll understand.
Yet we only have recollection of the Uchiha and the Senju fighting since the
Feudal era . The only known battles before existed between Indra and Asura's transmigrates via common sense that those two have fought between generations. Kishimoto already explained that the Senju's were the dominate one's in the War.
