The Trumpeter
After a battle, a trumpeter tried to bargain for his freedom. "Do not kill me, for I carry no weapons and slain no man! Indeed, I have nothing but this trumpet!" "Indeed, and for that reason you will be put to death immediately, for you have sent more men to their deaths than the greatest warrior!"
Hence it is said: Instigator tam malum est malignis.
Notes
This is another one of the Aesopic stories I remembered from when I was young.
