It’s meant to be a story of accepting your heritage regardless of the fact they were horrific. Not blaming yourself for those sins, and doing your best regardless so you can leave that heritage in a better state for your children.

Remember DBZ was written by a Japanese man. For as much as DBZ is a silly shonen about muscular men beating each other to death and screaming.

It’s also a story about honor, heritage, family, and self improvement.

Kakarot is very close to a case of finding out your adopted and your fathers last name was Hitler.

Realizing you arnt like your father, improving yourself and making a fresh clean start to the name. So both your adoptive family and your blood families name are honorable and clean.

And that your kids will be proud to share a name with a good man, for he proves that we are all masters of our own density and actions. That your forefathers do not define you.
