As Zoro's number one fan I can confidently say this is more distressing than after Nothing Happened.
Zoro's story isn't done quite yet. Oda intentionally shows Onimaru viewing in the screen in Ringo, and I'm sure the next few sequences of events will lead Zoro to Ryuma's grave.
Wait... so you're telling us everyone in Wano is watching an event at the Flower Capital...
This is just way too perfect to not be used in a bigger more climatic way, opposed to Luffy beating Kaidou with only Yamato and Momo watching.
The signs are there folks, Kaidou and Big might rise from the dead and return from Hell.
In the Flower Capital in front of the whole country of Wano. Kid, Luffy and Law will defeat Big Mom and Kaidou for good.
