Honestly? At this point, Kizaru can stay away from Zoro, if you ask me. Let Saturn kill him for failing to meet expectations and illustrate how "evul" he is, for all I care. Despite all the people that clown on Lucci, at least Luffy "three-pieced" him without causing lasting brain damage or contiously humilating him.
Kizaru is getting washed and tossed aside like dirty laundry this chapter, while Luffy's focus is on Saturn in this fight.
