Zoro is all about duels and fightin uphill battles and overcoming them.
Anyon who says zoro is fine and still decided to go inside the building knowing well what IMU did to him don't understand Zoro character at all.
He's the man who got pierced by Killer and still moved forward to KO killer and then went down.
As long as Zoro is capable to fight, he will get up and fight.
So, if Zoro is getting into the building then it's clear - he's injured and needs treatment.
No amount of cope can change the reality.
One should gracefully take L instead of making more of a fool of themselves by coming out of weird cope.
