So is the criminal mind attracted to the porn or does the porn create the criminal mind?
Can't read the article, my eyesight, you know.
After a preliminary scan of this article, It would seem the dominant (pun unintended) thought process is POWER.
Not NUDITY, NOT SEXUAL RELATIONS, but POWER over another.
Most or all of these killers and abusers (IMHO) are dealing with FRUSTRATION. They see themselves as having a lack of power over others (preventing them from getting satisfaction, sexually or otherwise), and they find sources of others attaining that POWER.
They then eventually decide since others can use their POWER to dominate and achieve satisfaction, that they can too. In that respect, the pornography supports and fuels their crime.
A lot of minds are attracted to porn, some of them criminal, some of them not.
Most sexual predators use knives, too but I don't hear a cry to outlaw those.
Rape is a crime of violence, control and power. The sex part is a means to an ends for these sick people.
