You love quoting me with shit that doesn’t help your points lol. What is your point? I guess we can’t always take what the characters say at face value, so it’s possible that Kidd takes down Big Mom even though Luffy said he would after all right?
Luffy actually makes multiple promise, to Katakuri, and Big Mom herself, that's he gonna come back AFTER BEATING KAIDOU, and defeat Big Mom. That's better than anything Kid has said. Need I remind you, Kid hasn't said anything about defeating the Yonkou when he's infront of the Enemies. He only dared saying that when nobody is around.
