You just essentially summarized every villains end result in Dragon Ball Z bro
Saiyans - take over earth nope
Frieza - immortality, ruler of the universe nope
Cell - gets destroyed, Goku gets wished to life, androids brought back to life, Trunks timeline is saved
Buu - destroyed, everyone wished back
No villain in the history of the series has ever actually done anything of negative value but Zumasu has clearly been the most impactful in his goal, as he has wiped an entire timeline. And who's to say he's failed yet, the theory of choice currently is that the Grand Priest is operating under very similar beliefs as Zamasu did. We might still be in the Zero Mortals plan, or at least a revision of it
