Sick "People's temple"

Right now, I am watching the climax of a documentary in History channel. It is about a mass suicide by a cult called "People's Temple". You can read more about this at
People's Temple - The cult
Jonestown - The location of the cult
Jim Jones - The founder

The documentary left me shaken to death. The documentary showed all (dramatized) events beginning with the establishment of the cult, the atrocities at the cult, the events that led to the mass murder-suicide in Jonestown, the very few people who escaped from death, the killing of US congressman and NBC reporters in Jonestown.

Makes me feel that all the billions of people in this world are perfectly normal, except for weirdos like Jim Jones/Hitler-kind of psychopaths.
