[DragonBall] How would the other gods of destruction and universes react if Buu had killed Shin and thereby killed Beerus as well?

Speaking of which, why didn't shin seek help from any of the higher ups, beerus would probably not decline to help since his life as well were on the line.

Most of them probably wouldn't have done anything at all and would probably have considered it to be Beerus' fault for sleeping through such an important event. The universes seem to be fairly insular and don't really meddle with the affairs of one another all that much.

There's a chance that Champa *may* have gone over to Universe 7 to Destroy Buu once he learned Beerus had been killed but that would be a personal revenge thing rather than something done in an official capacity as a deity.

By the time Buu attacked the Kais, Shin was nowhere near finished in his training. At the time, he may not have even known there was anyone he could have gone to (he didn't seem to know who Zeno was until Elder Kai told him) and he probably had no idea how to contact Whis or Beerus (who was asleep at the time anyway) regardless.
