If death isn't a big deal in Dragonball...

...why was Goku willing to give up his existence (when he fused with Vegeta) to defeat Buu?
I mean, the ones Buu would kill wouldn't cease existing, but Goku would cease existing by
staying fused forever. So it was not worth the sacrifice.

 

[Let's Go Fearless!]

The universe will be destroy and Boo will soon destroy the afterlife as well, so it's worth it.

Pain. It'd fucking hurt being killed by Boo, so he wanted to avoid that fate for billions of earthlings.

Yeah death isn't finite in the dragonball world, but they sure try to avoid doing it if they can.
