No he said if Luffy ever done anything to get in his way Zoro himself would kill him.
And that's the least Luffys ungrateful pathetic ass can do for Zoro. He still hasn't earned the right to he Zoros captain when Zoro STILL had to save his ass with Hakai, as if Thriller Bark wasn't enough.
If Luffy had even an ounce of moral compass he would step down and let Zoro be the captain.
Luffy owes Zoro everything
Zoro owes Luffy nothing
Get your BS headcannon out of here.
Stephen Paul's Translation
Zoro: I'll be a pirate... I PROMISE!!
If I'm gonna battle with these guys, I might as well go into full villain mode anyways...
But you need to understand, I've got aspirations!!!
I'M GOING TO BE THE WORLD'S GREATEST SWORDSMAN!!!!
I don't have to bother with the "purity" of my name!!
Whether hero or villain,
everyone in the entire world is gonna know my name!!!
You invited me to join!! If anything happens that causes me to give up my goals...
You have to disembowel yourself in apology!!!
