snuff

The snuff movies,also known like the real thing,
have a extrem content where the people are tortured,
raped and killed for the sole purpose of saving this
bloody images.This cinematic genre is a myth and there are many urban legends about the snuff.

This rumour of the existense of this type of films
began in 70's when Charles Manson stole a tv truck for burn all the murders that he committed.
The first film to be marketed as gender snuff, in 1971,
was about the murders of Manson, this are so rude, for this reason this movie can't be able for saw in the cinema until 1976,
when the directors, Michael y Roberta Findlay ,introduced more images with violent content.
This film did a huge scandal in the public,
and for this reason the movie was investigated for the police
until they discovered that all the film are do it with special effects.

But my question is
There are people so ill as to excitarse and enjoy seeing
how people are killed?
