Part 3
For the other Dragonball characters, their characters are the same, both good and bad qualities.
The main thing that will be addressed with the characters is the rape culture that all of the characters are involved in from behavior written as jokes to problematic behavior that is either missed/ignored in it's entirety, as well as consent violations. The most obvious one is Master Roshi a pervert who molests women (and girls since he hit on 16-year-old Bulma). As a child, Goku would touch girls to figure out their gender and took off Bulma's underwear while she was unconscious to understand hat a girl was. Bulma weaponized her sexuality to try to get anything she wanted and somehow didn't notice that her underwear was gone for several episodes. Also, she tried to seduce 12-year-old Goku, which is sexual abuse of a minor. Vegeta does not really respect women. Chi-Chi blackmailed Goku into a date. Gohan was blackmailed twice, once by Videl. Also, although it would have been best if Gohan dodged the kiss in Super, it is also a fact that he was assaulted by her. This list could probably go on for a while.
Lastly, I want to consider what it means to be worthy and pure of heart. Being worthy is probably a bit more complex than being pure of heart, but I think that the main idea is that the characters which are worthy is that they are remarkable and exceptional in their actions and how they help/serve others. For being pure of heart, I feel like these are the characters that mean well and have the best of intentions, even when they make mistakes. These characters do not have bad intentions toward others and only fight/kill those with bad intentions.
