This quote is taken from an interview of sensei, circa 2014/25 the question and answer on Vegeta and the sense of family is as follows:
- Q: Since Saiyans are supposed to have no affection for family or friends, does this actually make Vegeta, who holds his family and wife dear, an even stranger (kinder) Saiyan than Goku?
- A :Vegeta, whose pride had been deeply wounded, sought help from Bulma, and little by little, his ruthless personality changed. Nowadays, you certainly might be able to say that. On the other hand, Goku might not have a sense of family members like Gohan and Chi-Chi except as one of his companions.
