I could never be a mass murderer. Mass murder is gauche. Mass murder is to serial killing as McDonald’s is to Peter Luger. Both establishments serve chopped beef, but one is indiscriminate to the point of ubiquity whereas the other is carnal dining at its bespoke finest. It’s not merely a question of quantity. A mass murderer is blind to attachment; a serial killer, however, holds a close relationship with his or her victims.
