In fact, before Yamato knew that Cardo would really commit suicide, she was at best a rebellious child, not a "rebel". It is true that Yamato worships Yutian, wants to be Yutian, and even wants to realize Yutian. These are aimed at her parents, but that doesn't mean she is wrong. Children are not the accessories of their parents, so there is no need to unconditionally support and obey their parents' behavior. Cardo is a scum, but it doesn't mean that his children are old and have no choice but to be scum like him. Yamato can aspire to be a smart, open and honest person and a "real man" like Ota. It should be noted that Yamato is determined to become an Ota and put it into action, but she has not completely let go of her feelings.

Although Yamato took the initiative to join Luffy's camp and kept saying that he would personally beat his father, he still had some confidence in the love between father and daughter. After all, before the handcuffs were taken off by Luffy and kloc- 15/, until the handcuffs were reconciled, she still didn't believe that her father would really commit suicide. Kloc- 15/, her last affection and trust for her father was completely blown away, and the unprecedented grief made Yamato shout out "Yan Yi", which also limited her father-daughter relationship with Kaiduo to blood. As she told Urti, she really doesn't care if Kado is dead or alive.

A series of actions by Cardo's own daughter are too big to deserve the word "father". Because Kaiduo is a scum, naturally he can't educate Yamato for the purpose of "taking children to travel", but he has lost Yamato's "understanding" and found the object of worship, so he won't be like Kaiduo. Boxing forces her to "distinguish between good and evil", and those who educate their children with scum as their ultimate goal are naturally not worthy of being parents.

There is no blood relationship between Cardo and Yamato. He raised Kazuo only to use her (for example, to make Yamato a peaceful country, thus consolidating Kaduo's own peaceful country. In the eyes of Kaiduo and Yamato, it is not so much his daughter or son as a "tool to inherit his own blood", so Kaiduo will put explosive handcuffs on Yamato, because once Yamato really leaves the country of peace,

Some readers tried their best to whitewash Kaido, and even said that Kaido was "spoiled" by Yamato, who wanted to be a man and treat her as his son, and Yamato wanted to be Yutian. Because Kay's so-called "pet" to Daiwa is just using her to complete her plan. Once Yamato can't finish Kado, she will die. Since Cardo, as a father, can kill his daughter without hesitation, as his daughter.
