Super nerd alert as I was a huge fan of dragonball Z as a kid. Goku tended to want to believe in the better nature of people to a fault, but anyone who betrayed that he would go on to attack. Two examples being when his brother asked for mercy and then Goku sacrificed himself to get him killed, and when Freeza did the same thing, Goku attacked with intent to kill him (but he somehow survived in space to become a cyborg). Many he didn't attempt to kill he had disabled like Vegeta's right hand man or the Ginyu force and they were no longer a threat, or he wasn't able to kill like Cell and supported and encouraged someone who was strong enough to kill him.

Point being, Goku doesn't have one of those no kill codes but he's merciful. Once someone is neutralized as a threat he sees no reason to keep being violent towards them. That's why if someone refuses to repent or just has no inclination to repent at all he works towards either injuring them to the point of neutralization or if they're too dangerous even then, killing them. Probably the only exception here is Vegeta. But you could argue Vegeta never really betrayed the mercy he was shown. I don't think Goku is a great example of what Qtoad was talking about
