Granted he may have had duties but just because he had a job doesn't change the fact that what he was doing was wrong. Psi Corps committed multiple atrocities against their own fellow psychics, even running a plot to take over the Earth Government which is treason. I mean even Nazi soldiers who were ordered to massacre the Jews, doesn't all of a sudden negates responsibility for what they were doing just because they were following orders. Later on after the Psi-Corps had been destroyed in the telepath war, Bester was hunted down and captured for War Crimes. So Yes, all this makes him a villain.
