It's factual. They are better fathers to children who are not their own than their own ones lol. Biological fathers treat their children terribly in OP! Mothers are definitely more favourable in general except for Big Mom and thus even her own mother and Carmel ofc? Oh Baby 5's mother too ofc! Trying to remember who else...
Whitebeard might look a lot worse depending on Weevil being his real son or not and what happened to Weevil then too. I theorise he was dead and has been brought back , as his scars remind me of Hogback's zombie work, we saw the Mountain Boar God get sliced in half and then stitched back together which Oda commented on the SBS or whatever recently, by saying if you cut something so cleanly, so precisely enough, you can just "stitch/attach it back together"? I think that's what happened with Law losing his arm and getting back too? I can't remember if Leo helped Law get his arm back with his sew/stitch fruit or not?
Weevil's character has insane potential depending on how Oda handles him, what he has planned for him. I just dread he might end up making Whitebeard look a lot worse but hopefully just more tragic and understandable maybe? Maybe Weevil was his real son that he lost in the past? So Thatch's and Ace's deaths would have been even more traumatic for him to experience, especially as Ace was the son of his beloved rival and it happened right in front of him too, despite all his best efforts to try to save him?
There's truly something ironic and yet heartwarming, inspiring and such about all these legendary men being such great fathers to children who aren't their own too!:
