Are there different types of psychopaths?

In class lately we have been disscussing that Eric was a psychopath; however, my question is, How many psychopaths are out there and are there different types of psychopaths that feel different emotions?
I researched my questions and discovered that psychopaths are similar to conciensious people in that they are all different. Some are motivated by blood and power such as Eric was, and others are motivated by success in a job. However, their erie ability to not be discovered for what they are makes it difficult to identify and study a psychopath. I found out that 4% of the world's population is; to some extent, a psychopath. That means 4 in every 100 people have some sort of psychopathy. It has been researched that people in politics might have a rather large ratio of psychopaths versus normal, concientious people. If you think about that, that almost makes sense. Politicians are steriotyped as being unremorsefull human beings with absolutely no worry about what happens to their opponent. The amount of psychopaths in politics would help to create this steriotype. From my reading it seems that there are many different grades of psychopathic behavior but they all stem from the same lack of concience. Some scientists argue that psychopaths should be classified as a different type of human.  Psychopaths seem to realize that something is wrong with them and they know that the difference is their emotional status compared to the rest of society. However, psychopaths do not feel the need to conform, they see no reason to change themselves. That does make it interesting that psychopaths do tend to act like they conform but in actuallity, they simply inspire trust or "friendship" in other people to get what they want. The act of friendship may not be a conformity but rather a strategy of getting what they want. Overall, the average psychopath has no feelings and they tend to be either criminals or very successful people. The successful people are known for their easy way that they cope with emotional problems. The criminals are simply written off as psychopaths and left alone. Psychopaths are out there and they are prominent in society, they affect people's lives both directly and indirectly. This and the fact that they hide their psychopathy is what makes them so dangerous and frightening.
