Honestly, both "Zoro is gonna fight King" or "Zoro is gonna return to fight Kaidou" have their own legit reasons to believe in their cause.
For instances, people said Zoro will not return to Kaidou just because he trust Luffy. But there's other instances in the story itself to support otherwise, like in Thriller Bark
He trusts Luffy, but he knows that they can't leave everything into Luffy's own hands.
