There are 2 options.
1. Zoro can end this but chooses not to.
2. Zoro can't end this like he wants to.
Zoro comes out looking bad either way.
In 1, he is endangering the crew who are trying to escape, and could have helped earlier when they needed it. He's also wasting Jimbe's time who could be fighting underwater against the fleet instead.
In 2, he's underperforming and is further from Mihawk than we thought.
