Is Hakai a technique impossible for Goku to master?


In the last chapter of the Dragon Ball Super manga,

> Beerus says that for using hakai he has to think only in destruction

Goku apparently tried to use hakai in the past, but it seems that he didnt
master it since he says he failed using it.

Also, according to Dragon Ball, Goku can use the flying nimbus because he has
a pure heart. Can a person like Goku with a pure heart do what Beerus says he
has to do to use hakai?

Is Hakai a technique impossible for Goku to master?




No, for now. Hakai is a technique that can only be achieved by a god of
destruction. If you are not a god it is impossible to master the hakai
technique. But that's only looking from the anime. In the manga Goku is able
to learn hakai in a fight against fused zamasu. Sadly in the manga debut
Toriyama hasn't confirmed Goku learning hakai to be canon.
