The study of psychopathy is a relatively new science, if you can call it a science. In my opinion its a study of peoples behaviour and past experiences with a fancy name given to it.
Its a science that is still in its infancy and should not be used as a forensic tool to justify who is and who isn't a psychopath just because they have ticked a few boxes. I believe that many of us could tick some of the boxes, but we are not psychopaths. Its believed that 3% of people living in England have this trait and just as many of us on a scale 1 to 10 have some psychopathy in us.
Some say Jeremy has no empathy or feelings, but this is not true. He was deeply upset and cried buckets when Brambles his dog died so when did he become detached?
Saying he is a psychopath when none of us has met him, chatted to him, or seen him is a perfect example of what we are led to believe by reading stuff on the internet, books, television programs etc. Its not that there is no truth in it, its a fascinating subject, but is it the bees knees way of categorising people for how they have lived in the past or present?
