This. This marks the beginning of Vegeta’s uh, obsessive, neurotic, all consuming, vengeful fixation on Goku. It’s intensity is almost always lost on Western audiences, but “yurusan”, translated to “unforgivable”, packs an EPIC punch in the Japanese language, and lays the linguistic ground for Vegeta’s villainous breakdown.
I mean, go figure that Vegeta loses his shit so bad that he then tries to vaporize the Earth—along with his own escape pod and atmosphere to breathe in. (For some reason, I don’t usually see this pointed out?) In that breakdown, Vegeta would rather that they both died than let Goku live for his “transgressions”.
