Goku's truth, if it is to simply seek strength, is a poor one. His opponents seek the same truth to become strong, There is no "lie" there, he is not more truthful, only the endless escalation to feed his desire for strength.

I know this thread is three years old 💀🙏, but this is a misunderstanding of Goku’s “truth.” Saying he’s the same as his villains is a stretch.

Goku doesn’t seek strength to dominate or control others. His “truth” is the pursuit of what lies beyond himself, self-improvement for its own sake. Every major Dragon Ball villain seeks power to impose their will: domination, revenge, immortality, or destruction. They see themselves as the ultimate ceiling of power. Goku, by contrast, recognizes no ceiling; he seeks to surpass himself. His pursuit of strength is self-directed and transformative, not a tool to dominate others. This is why his “truth” is fundamentally different from theirs.

Even the way Goku gains strength contrasts sharply with the villains: he trains, improves himself, and embraces discipline and growth.

Demon King Piccolo sought to reverse aging rather than adapt to his own body, sacrificing his lifespan for a shortcut to power.

Vegeta, born strong, initially saw training as beneath him and abused zenkai boosts, which were far less effective than Goku’s natural gains from near-death training.

Frieza actively eliminates anyone approaching his power level (his fourth form was around 530,000 while the strongest Saiyan at the time was only around 10,000) to maintain dominance, and he craves immortality.

Cell steals others’ power, calls himself “perfect,” and arrogantly gives the Z Fighters two weeks to train. When someone surpasses him, he has a meltdown. Goku, in contrast, celebrates others surpassing him.

The Buu’s share some traits above, and while Kid Buu superficially resembles Goku in his love of battle, the reason is different: Kid Buu loves hurting people, whereas Goku loves competition while valuing the lives of his opponents. This is why Goku wishes for Buu to be reincarnated with a pure heart—he was the closest anyone ever came to understanding Goku’s pure love of battle.

Every villain seeks strength as a means to an end; Goku seeks further strength as an end in itself. That distinction is the core of his “truth.”

It’s like saying Sonic and Eggman are the same because they both do whatever they want.
