Unless, again, Big Mom. If Whitebeard has to contend with Kaido and Big Mom, he might have felt it wise to not commit to it.
I never said that there’s not many scenarios that could play out, only the most likely, reasonable, and certainly not dumb one is that Whitebeard was going to kill Kaido (as he’s started a war over one of his crew before) and Big Mom stepped in and saved Kaido. There’s no reason to get so salty about it.
You sound like a child. Just saying.
