One thing that Minus and Broly retconned was that Goku is the same age as Vegeta. Goku landing as a baby came from the anime, it never was in the manga (the head bump as a child is only mentioned once by Raditz, I don't think the manga ever showed it), and Minus/Broly showed Goku being about 5, like Vegeta, not a baby.
If I struggled to the end of my determination, to the end of my way of life with my followers, if the result is ruin, then this ruin is inevitable. Grieve. Shed tears. But you cannot regret.
