Do you believe that Raditz felt that his mother and father were weak for becoming so close with each other? And I don't mean to spread hate to other anons, but I think people often overlook the fact that he was still a full-blooded Saiyan who was raised in a violent environment. he is most definitely not friendlier than Nappa or Vegeta! Since all three of them were jerks who enjoyed hurting other people, He wasn't a teddy bear like his brother.
I don't think so. You don't tend to think of the environment you're raised in as the odd one, but I also don't think he spent a ton of time in Saiyan society, so he might've just decided that's what his parents were like and the FF is just built different. He's not squishy like his brother, but Bardock isn't squishy either, he's just bonded to his partner.
That said, a lot of the lower classes seem to be pretty neighborly as they're depicted in Chapter Minus, so Raditz was born into a more community-minded environment than Vegeta and Nappa overall. He probably didn't know there was a difference in how Gine regarded other Saiyans (which seems to be pretty much also how Toriyama's Goku reads relationships, too. He knows on paper there are different categories but he doesn't care about them. He just wants to snuggle the homies), he was very young when he left home and he was very young when she died.
Also worth noting for the sake of headcanons: Toriyama mentioned in an interview that they were a family but they were never all home at the same time. Raditz almost certainly never had a clear view of his parents' relationship. He was a little boy the last time he saw them, and they were lower classes, so it's not likely imo that the elites he was working with would've known them well either, if at all.
If Raditz thought his parents were weak, it would probably be due to the fact that he outranked them both as a kid, not because they lived together. And even so, he stayed in contact with his mother, and Vegeta remembers Bardock was the name of the boys' father a full decade and some change after Raditz died, so he must have heard it often enough to stick. Personally, I don't think Raditz felt any disrespect toward his folks. As I mentioned in my other post, I do think he is softer than both Nappa and Vegeta, in the same way a coconut is technically softer than a stone. You'd break your teeth on either one.
I think I also mentioned in the other post that without his brand of softness, I think the series would've ended with his introduction. He came to Earth because he remembered his brother and came back for him. He wanted Goku on his team, and he offered not to kill Gohan on the grounds that he was Gohan's uncle. Raditz was always more open to community bonding than Vegeta and Nappa were (and Nappa more prone to troop bonding than Vegeta was). They are extremely ruthless in comparison to Earthlings, but they're all squishy compared to Freeza. In terms of cruelty and cold-hearted nature, Raditz is closer to Nappa than he is to Goku, but he's closer to Goku than he is Vegeta (who has slowly become closer to Piccolo than he was Freeza).
It's a spectrum, not a switch, if that makes sense.
It's also worth noting Goku himself is not a teddy bear. He is very much a normal bear, he's just well fed and raised on positive interactions with humans. He won't kill for sport or entertainment, but if he decides you're a problem he can't solve a better way, he will kill you and he won't lose sleep about it. He might also eat you, if he's hungry enough. Saiyans gotta get fed.
