Vitally important information.

Scientific studies show that psychopaths' brains work in very different ways to the brains of normal human beings. According to Robert Hare, the psychopath seems to interpret, process and use emotional information as if it was neutral information. The psychopath cannot extract emotional information from words as normal people do. Words like "murder, rape and death", provoke NO reaction in the mind/brain of a psychopath. They respond 'in a very superficial manner' to concepts that cause an emotional and distressing reaction in normal people.
