Where do you think he learned it from?
What do you think motivated the Roman public to support the destruction of Judea?
Lol so now your answer is wild baseless assumptions? Nero’s tutors were Greek and Roman, including most notably Seneca. Everyone he came into contact with for any meaningful amount of time was Greek or Roman from childhood on. If you have evidence for your claims then provide it.
I know what motivated the Roman people to support the destruction of Judea, it was the same thing that motivated them to support the destruction of Gaul and Thrace and Carthage and all the rest.
Why don’t you stop implying and actually say something so I can prove how silly your theories are?
