Well, Sky Yellow sounded more offensive or something, in my opinion. From what I understand, Judge's "surgery" was supposed to deprive empathy from all four of his sons while giving unique abilities to each of them before Sora's drug kept Sanji from being modified. He probably used something similar on Reiju, but she still has her empathy.
