Why is Zen Oh Sama destroying universes?


Why are the Zen-Ohs going to destroy the universes that lose in the tournament
of Power ? It seems rather brutal and pointless, and make the Zen-Ohs look
evil just for the sake of being evil.




By now the anime has provided a clear answer (though if you're only following
the broadcast of the dub you're not quite to it yet):

> The whole tournament and super dragonball wish was a secret test of
> character. Wishing back all of the universes was essentially the only
> correct and allowed wish. If a selfish wish had been made, they were going
> to take it as proof that those Universes are, in fact, not worth keeping,
> and all of them would be destroyed. But wishing them back would be a
> testament to the caliber of the denizens of these universes, such that they
> would be returned and spared.

Oddly, this seems to be a little different in the manga:

> None of the "secret test of character" stuff gets brought up at all.
> Seventeen says he wants to wish all the universes back if the super
> dragonballs can do so, and the Grand Minister confirms that they can. So
> they're wished back and that's pretty much the end of it. All that's said is
> that the wish elevated Universe 7's rank by one position. Which does at
> least say that such a wish was (highly?) valued, but not nearly at the level
> it seems to have been in the anime.
