I have no idea what the point of your post on Nero is from what you write it sounds like this.
Chazal state that Nero converted and Rebbi cam from him.
The Romans do not account for his end so most think he was either murdered or committed suicide (in other words they do not know his end).
OK, makes sense.
Do you honestly think that the Romans were going to tell the story of how an Emperor of their converted to one their main enemies?
