Honestly, Super Buu was not as dangerous as Kid Buu since he could actually be reasoned with.
Kid Buu has no leash, therefore nothing is stopping him from going full "Planet Buster" like he just did with Earth.
Hence my previous post. It made me believe everything was coming to an end.
Earth was supposed to be in one piece, but it wasn't when Kid Buu came along.
Hopefully so.
Also, another note: Wasn't Beerus against anybody meddling with time travel in the first place? If so, why isn't he raving mad at Zamasu since he is doing the same thing?
Goku also wouldn't go into battle blindly back in DBZ. He even prevented Gohan from trying to run off and fight Imperfect Cell because he knew that they wouldn't be a match for him.
