Who exactly is Piccolo Jr. to Piccolo Daimao?

[kaialone]

Uub, despite having Buu`s soul, doesn`t have any of his memories. So, there is no reason for him to be evil just because he was Buu in his previous life.

Dragon Ball follows the idea that a soul, a person, is not automatically evil or good when that person is born. It just becomes good or evil as the person goes through life.

In that aspect, Buu is an exception, because thanks to Babidi`s father`s magic, he was born evil.
But when he was killed, his soul followed the rule of all souls. It was cleansed and his memories were erased to be reincarnated as another person, neither evil or good at the moment of birth.

Piccolo Daimao on the other hand didn`t have a normal reincarnation. His soul wasn`t cleansed and his memories weren`t erased. That is why Piccolo Jr was born evil.
But his reincarnation did change things. He was Piccolo Daimao but, at the same time, he was also his son. He was Piccolo Daimao and something else at the same time. That provided him enough "room" in his personality to be allowed to be influenced by Goku and Gohan`s kindness and good in general. And thus he eventually changed and became good.

Yeah,I didnt think of that.I´m sorry I should think more before throwing a comment into the room

To me Piccolo Jr is his own being.
He was just as much a son to Daimao, as his brothers Drum, Piano, and Cymbal.
I also believe he originally had his own soul, but Daimao "fused" his soul with it when he died.

This way it would make sense for Piccolo Daimao's part to be dominant in Piccolo Jr's early years.
But as time went by, Piccolo's own soul got time to grow and experience the good things in life, like love and friendship and all that shit.

So I guess he went through the same thing as the Son of Katatz .
Katatz had a pure soul who got corrupted with evil, while Piccolo Jr's soul was an evil one that got corrupted by good.
