#bulma is the most beautiful woman and vegeta praises every day for being her husband

[saiyanmazen]

What if Vegeta loves that his children don't look like Saiyans?

What if his own self hatred and his own illusions about what Saiyans were have caused him to hate looking at anyone resembling Saiyans?

That, despite all his talk about Saiyan superiority, he has nothing for revulsion left for his dead race.

Seeing Kakarot - hell, even Yamcha’s Saiyan-like features - disgusts him because it reminds him of his failed race and how everything he was taught was wrong.

Even looking into a mirror repulses him because he has to face everything he and his people have done.

So, seeing his children with their human features - looking more like their gorgeous mother - fills him with joy.
