I dont think Yamato can grow like this without anyone interefering.
So either someone interefers and tells her to drop her BS maybe someone who has undergone identity crisis themselves?
Or an incident makes her change it.
Otherwise Oda will use thsi as worst gag.
But even for current writing style this seems to low to use it as gag.
But honestly Yamato in anime is just so nice already.
I am damn sure the anime will elevaet her fight with Kaido to level beyond our thinking as by that time in manga well prolly be at other arc
