Simply speaking, the brain of a psychopath lacks the Humanity Centre that the rest of us have, which is in the Human part of our heads. The Humanity Centre contains areas that evoke such things as guilt, remorse, compassion, empathy and conscience. Psychopaths are typically just cold and calculating individuals that use others to their advantage. So is a psychopath really responsible or not for their actions? There is a great deal of argument about this, but whatever we believe, there is a lot of evidence that this centre in the brain is either absent or asleep.
