Kinda like Goku throwing Cell a senzu bean? Or him allowing Frieza to power up to 100%? Or him letting the fate of the world rest in the hands of an 11 year old? Gohan is a millennial disappointment, he doesn't bear mentioning. Fact is, guys who only care about fighting the strongest only save Earth because its there, not that they give af. Goku's character in the manga ain't a hero of justice, he literally just wants to fight strong guys. Not too mention him telling Krillin to let Vegeta live in the first place!
