So as everyone of those you worked with would have been totally different, what, in your estimation, is the common denominator of psychopathy?
Wthout an EEG or MRI there's no way of knowing and the way a person behaves isn't one way of telling.
It's not something that can be diagnosed unless a person has murdered multiple people such as Sutcliffe and those like him.
Because Jeremy doesn't show or display remorse is NOT a symptom of psychopathy in HIS case simply because he didn't do anything.
Patients at the hospital were downright cruel to those who were vulnerable and usually ended up in the padded cell because of their continual urge to inflict pain,and who enjoyed doing it. It's this wanton cruelty that points towards psychopathy and can be seen in children from an early age. It's part of a marker that follows into adult life. Those who get a kick out of inflicting pain !! The fearless ones.
