Man, from what we could see, Goku is the one who will end Moro, even tho' I kinda liked this episode, I can see the amount of Hate coming from Vegeta's fans over this.
What, you're telling me Goku couldn't just tingle his back / make himself angry to unlock full MUI just like the universe 6 saiyans did with SSJ1 and SSJ2?

I think this is the first time someone is dying on Goku for real in a loong time. The same kind of push he needed to become super saiyan and now to master ultra instinct
