I always have a hard time watching many serial killer movies if for no other reason than serial killers exist, and the crimes depicted onscreen could and sometimes do happen to real people. In serial killer movies in particular, much of the violence is directed towards women, which makes my viewing experience more difficult.

They do not kill for reasons society considers “justifiable.” They seem to do the unthinkable, killing for pure personal gain, for profit, or to fulfill some twisted sense of morality. It seems to go against all human decency to kill so needlessly and frequently.
Our fascination expresses itself with many questions—how does the killer select his victims? Why those victims? How does he kill them? How long has he been doing this? How has he never been caught? Yet those questions come secondary to the ten-million-dollar question:
