Yeah that shit made no sense lmao.
That magistrate is the slasher so Zoro suddenly turns into a Vigilante who brings people in power to justice? That too when he's supposed to be undercover?
One way of explaining it would be that he had to fight and get out of his own execution... but honestly I just think Oda drew that shit because he thought it'd look "cool" or something.
A lot of Oda's writing in regards to Zoro post Timeskip has been awful
The Monet thing
Zoro walking around in public in Wano with Ryuma's sword when he knew from Kinemon how sacred it is to them
Killing that guy
Nearly ruining Yasiue's sacrifice because he couldn't control his anger
Wanting to kill people over soup when unlike Luffy he doesn't have any attachment to Tama
The fact that he apparently was missing around with Apoo untill He saw Kiku's arm
It's hard to take Zoro's "this is the New World" shit seriously
