The fact that this gluttonous woman could become one of the future Four Emperors and rule over the Grand Line in the great age of piracy said a great deal in itself.
She had a fairly clear understanding when it came to judging situations and other matters, provided sweets were not involved.
Whitebeard's prestige had been forged through battle after battle. Even if Marco had spoken disrespectfully, Whitebeard was still in his prime. Killing him over a few harsh words would clearly have been unwise.
Besides, given Marco's Fruit ability, whether they could even kill him was another matter entirely.
After weighing her options, this rare female among the great pirates merely taught him a lesson and left it at that.
Naturally, for Marco, who possessed the Phoenix Fruit, injuries of that severity were hardly any different from no injuries at all.
As for Wald, the little sweets deal he had proposed could not move Big Mom in the slightest. And any normal person knew which side to choose when it came to opposing Whitebeard for the sake of a beaten stray.
Thus, Wald, wielder of the More-More Fruit, known as the "Destroyer of the World" and once a great pirate second only to the likes of Whitebeard, continued farther down his tragic path.
Still, the fact that he had endured the Whitebeard Pirates' continuous attacks for so long and could still flee wildly through the New World proved just how powerful Wald had once been.
But as time passed and the strength of his entire pirate fleet was nearly exhausted, Wald finally could not hold on any longer.
With no other choice, he decided to withdraw from the New World and temporarily return to the first half of the Grand Line to recuperate.
Whitebeard naturally would not stand by
