I thought it was interesting how Oda chose to depict all the expressions of the Roof 5, watching Zoro block Hakai.
At this point Zoro has already said what he needed.
Even with Luffy's pleading, he tells them to just go, "we can't let them wipe us all out!!"
That's all Kid and Killer needed to hear they are "sprinting for the door" in their panels, resigned to abandoning Zoro. Makes sense since Kid and Killer have their own dreams and they don't know Zoro too well.
And then law’s like “I’m not running, but I’m definitely not staying, I’ve got a smarter idea”
But you also have Luffy, even after Zoro told Luffy to go, he is still just watching. If Law wasn't there to switch, would Luffy have eventually ran and dodged. As Zoro says, it is important to live on, in order to continue to fight and defeat Kaido, but I think Luffy would jump in and tag team it with Zoro, live or die.
Often times we talk about Zoro faith in Luffy and how he watch over him but seldom talk about the vice versa.
