I can buy that Mulciber was a bully from the fact that he became an animal executioner for the Ministry
Macnair was "an animal executioner for the Ministry". Information on Mulciber:
"Yes!" said Karkaroff. "There was Travers - he helped murder the McKinnons! Mulciber - he specialized in the Imperius Curse, forced countless people to do horrific things! Rookwood, who was a spy, and passed He-Who-Must-Not-Be Named useful information from inside the Ministry itself!" (GOF, ch. 30, The Pensieve) |
