>>104607173Goku is oblivious to social conventions, that's the joke. That's played out since episode one of Dragon Ball, and it goes from not knowing about female anatomy to accepting a marriage, without any clue about what this means. Before the Saiyan lore, he was quite literally a monkey-man, hence his mythological name. One recent example is him behaving like a kid in front of Zen-Oh. But let's not forget the context of the examples you gave. The whole mess about Goku dying and Piccolo having to take care of Gohan started after Goku giving his life to save, at this point, toddler Gohan.
Goku had no intention to make baby Gohan a warrior, and Piccolo took advantage of this, only to get frustrated on how much of a crybaby he was.
The whole point of the Saiyaman arc was to show ;
>Despite the best efforts of ChiChi, Gohan derailed his career into a justice warrior, just like his father>Besides not being dumb as his father, Gohan was not the smartest guy around, being tricked by Videl, a reverse ChiChi>In the end of the day Gohan would do anything to protect his family and friends, making him understand even more Goku motivationsGoku maybe is one of the most straight examples of the noble savage in media there is. His whole character is being a dumb, clumsy, amoral fool, at same time being the nicest person around. Despite Goku ignorance, lack of wit and clueless interactions, this is what gives him the pure heart that grants his victory.
If you think about it, every single major DB/DBZ villain was either a high-rank enemy, or part of one intellectual elite.
