KingKulami, First, Nero was actually loved by the lower class and hated by the senate even after his death. This is according to Roman historians such as Tacitus and even accepted by modern historians.
Second, the line was broken when Nero was killed. That's why the Year of the 4 emperors occurred after the death of Nero because there was no clear line of succession.
Third, just Rome the city itself revolting (even if it was possible) would not spread throughout the whole of the empire simply due to its sheer size and power. If this happened then some general would simply claim to be the new emperor and take Rome.
So, your POD is probably asb and not possible.
