I don't know, I feel like Oda wants to redeem the Vinsmokes and Judge really loved Sora but his obsession with strength transformed him into a bad father.
Judge values nobility and strength. There is little to no evidence he loved Sora, and even less he would've put marrying her before his own ambitions.
He would've only married her if doing so helped those ambitions along.
There's not much redemption to be had for him, not even in death.
The siblings will be redeemed. I think all of them will be part of Sanji's future floating restaurant. I essentially expect Sanji to end up a hybrid of Whitebeard and Big Mom - a massive family of all shapes and sizes, and a bunch of kids that are all his.
I think sora was evil and the vinsmokes wanted to unified the world so they started in the north but sora and imu defeated them by using their emotions against them that’s why judge wanted his sons emotionless
The Vinsmokes being good guys all along has no narrative value. Quite the opposite.
I think it's more likely the Sora of 300 years ago was in fact a heroic Marine figure and ancestors to Vinsmoke Sora.
I'd like to believe he was recognised for his exploits and made into an immortal Holy Knight yet to be revealed, and that Sora was the child of a concubine and therefore not a real CD, but nevertheless an appropriate reward for Judge for services rendered.
