Similarly, the Gemara explains that a Roman officer admitted that the reason they don’t wipe out all the Jews is becuase not all of them are in Roman controlled lands, and to kill only those under their rule would give them a bad name, a murderous regime.
The question is, if all the Jews were in Roman controlled lands and they would kill them all out, RL, they would have the same bad name. Why is it presented like two sides of the coin. My answer is that if they’d do what they want to the Jews nobody would bat an eyelash. It is only the remainingg Jews that would complain, causing their hosting governments to voice condemnations.
