Character Discussion Why didn’t Whitebeard marry Big Mom?

WB wanted a family

So did BM

I feel like they would have made a good couple. She would have at least been better than Stussy.
Well, Backin at least is always with her son, she cried when he was arrested.
She is a much better mom than Linlin (miles away)

Linlin is by far the worst mom of the series. She doesnt have problem in killing her sons. She killed one of them in the beggining of the arc, then she killed Opera. She was ready to kill Perospero (her first son). She humiliated pudding several times since her childhood. She didnt let any of the fathers of her sons and daughter meet the kids.
I really dont remember a worst mom than her in all fiction. Even Tama she tried to kill
