Zoro would never attempt to kill Sanji, at best injure him and even that's extensively questionable as a thought.
Regardless of anything, my point remains I suppose. He could have dodged that much more swiftly had he had the capability to.
Zoro and Sanji would never kill each other
and they DO NOT hate each other
BUUUUT
They respect each other very well that they go HARD on each other
In fact, I see Sanji going the hardest and have the strongest will scenes ONLY when he is around Zoro.... when he's not with Zoro, his competitiveness starts to become lacking... and his mental game starts to waver and shake... which is one of the biggest reasons why I put Zoro above Sanji in strength... it's because one has more will during fights than Sanji who honestly is a flawed character who may give up easier than Zoro... despite having a close set of skills for combat...
Anyway, when both combat each other, they go hard on each other because they respect each others well enough if you don't do that, the other might make a fool out of you by knocking you on the ground LOL....
That's how I view their relationship
Naturally other people will have different opinion
