By Z, it was practically routine to use the Dragon Balls out to undo any major consequences. Yeah, you had wishes like removing 18's bomb or giving Goku more energy in the middle of a tense fight, but more often than not, it was resurrecting anyone killed by the bad guys. Even the ending of Super hinged on 17 choosing to use the Super Dragon Balls to resurrect entire universes wiped out by the two Zenos. As in, if 17 didn't make this specific wish, the Zenos would wipe out every remaining universe in existence.
