The Daily Telegraph reporting on his trial said: "His nom de guerre came from a textbook story about "Duch" a model pupil who always had his hand raised.
"I liked the name Duch because I wanted to be the well disciplined boy who respected teachers, who wanted to do good deeds,"
I remember reading that Khieu Samphan, the number two in the Khmer Rouge was a well disciplined boy too, who never had a girlfriend, and who was constantly teased.
Therein is the mind of the psychopathic mass murderers who obey the state they helped create, and spill blood as if it were water. Typically not that different from the occasional teenager who takes a gun and shoots out his fellow students.
