Nothing of this really equals being imprisoned and made to work hard like Luffy nor what Yamato went through for all these years.
Having someone you bonded to and cared for dying fighting Kaido's regime right in front of your very eyes while saying how no one is able to take his (kaido's) head. That matters far, far, far more than Luffy doing some work in Udon lmao.
You're literally stupid if you think otherwise. Lmao. Would you rather have a friend you bonded with die or have fun training in some prison. Holy shit, Luffy doesn't even give a fuck about getting prisoned. Show me when he showed anger towards Kaido over it? He's angry because Kaido hurt people he cared for in Wano LOL
Imagine if Otama died right in front of Luffy's face; he wouldn't give a flying fuck about Udon compared to that. It's like that for Zoro.
