I did, there's nothing wrong with having a role model. What's wrong is trying to become that role model to the point where you lose your real self.
She still hasn't lost herself. She called herself, Yamato the son of Kaido multiple times. In her mind, becoming Oden ~ living as free as Oden did and inheriting Oden's will of saving Wano (in that panel where she even goes on to say that Luffy is more Oden than she is). I'm not a huge fan of this Oden act either but it isn't as twisted as you portray it to be.
She's basically still an 8 years old child, she didn't mature beyound the imitation act, she doesn't have her own goals, all of her goals are taken from oden's life and ambitions, does her longing for freedom comes from oden influence or from her own experience?
Nope.
After fangirling Oden as a child, her experiences changed her. Wanting to be free like Oden is from her own experience. She has been tied and cuffed to Wano for 20 years. She explicitly asks Kaido in the recent chapter "What right did you have to take away my freedom?". Her wanting to be free comes from that experience and that is why she idolizes Oden, as he is again someone who went on a grand adventure and detailed all of it in a logbook, which she claims is "her Bible". She wants to explore the world and be free and that is shown multiple times.
Also if she hates kaido that much then why does she have his exact move set, most one piece characters developed their unique combat style at a very young age, but yamato didn't.
This is a stupid criticism. All her combat experiences were from fighting Kaido. Ofcourse she would imitate his move set and overtime end up mastering it. That has nothing to do with Oden, Kaido, wanting to be Oden or hating Kaido.
Luffy also learnt the fighting style his grandfather uses and is a brawler like him. He even imitated Soru looking at CP9 and incorporated it as G2 in Enies Lobby.
Sanji hates Germa but still uses the Raid Suit.
Here's the thing, idolizing someone doesn't mean they have to be exactly like that person (which is one of the criticisms that you yourself aimed at Yamato). It is not just a coincidence that Oden's son is a Dragon and Kaido's son wants to be Oden.
