At least serial killer doccumentarys highlight the immorality of these killers ? look at the violent fictional entertainment americans seem to desire and recreate, which often seems externally, to show indifference to the presentation of criminality and aggression, combined with the approval of selfish patterns, extreme financial pressure, agressive socially and divisive … anything goes culture & increasing wealth gap, combined with a population of 300 million, means serial killers I think are inevitable.
