Lol i already told you in another thread - we already know Sarada became a ninja cause she had a headband on in the trailer and was in the chunin exam staduim so why are you even acting like she doesn't want to be a ninja when she already became one?
Clearly her mind on things changed, or do you think not even Naruto could motivate her?
She's a kid who knows, they are easily manipulated. But she is smart and strong I'm sure in her own views of thing. But knowing who her father is now and seeing how much he doesn't care for her will most likely resolve her own thoughts about being a Ninja lol.
Naruto's TNJ is strong but like Sasuke who left the Village in part one and Naruto couldn't convince him then, chances of convincing her to become strong for no reason is pretty unlikely.
For what reason does she to become strong? She followed Naruto to meet her deadbeat father only to realize her dreams were just that.
Naruto would need to be TNJing her hard to drum into her a spirit to become strong because as of now she don't to me have any reason to want to become strong.
