Nero might not have been anything like what his later biographers claimed. He was the last of his dynasty and the succeeding line had had a major part in his removal. Most of the surviving texts were preserved by Christian monks who had agendas of their own.
Quite possibly Nero just lost the confidence of the Senate because he lost territory on two fronts and was seen as weak and incompetent. They don’t like Nero because of the presumed execution of Paul and Peter under his rule.
Nero certainly had some role in the start of the Jewish war. He might well have ignited the revolt with his punishment of Jewish ‘Chrestians’ reported by Josephus which Christian authors subsequently claimed as a misspelling of Christian. There are other references to a Chrestus who was one of the leaders of a zealot faction that does not fit the accepted Jesus chronology (if he existed at all).
At least neither of those had nuclear weapons.
