In short, a wolf in sheep's clothing, a predator in disguise. Psychopaths are generally thought of as serial killers, but most are not even criminals; necktie psychopaths wreak havoc in the office, ruthlessly manipulating and charming their way to the top.
Psychopaths are obsessively meticulous, are calm and fearless, and are able to lead a double life in which family and friends see one person... and other people see a very different side. Immoral, perverse, and criminal, they know right from wrong but they get a thrill out of defying the law and moral codes.

It is time to note the difference between a psychopath and a psychotic.

Psychopath:

A person with an antisocial personality disorder, manifested in aggressive, perverted, criminal, or amoral behavior without empathy or remorse.

Psychopaths tend to lack normal human emotions such as guilt. They are also often highly intelligent and skilled at manipulating others.

Also, psychopaths seem to appear normal. You would probably never guess there was something wrong with them.

Note, not all psychopaths are serial killers.

A person who knows the difference between right and wrong, but doesn't give a damn. Shows no morality and no emotions towards others, including love, guilt or hatred. Would happily destroy anything or anyone merely for personal pleasure.

A psychopath is one who suffers from the anti-social personality disorder of Psychopathy.

A psychopath can be identified by using the PCL-R Checklist, which contains the following characteristic traits:

1. Superficial charm and above average intelligence.
2. Absence of delusions and other signs of irrational thinking.
3. Absence of nervousness or neurotic manifestations.
4. Unreliability.
5. Untruthfulness and insincerity.
6. Lack of remorse or shame.
7. Antisocial behavior without apparent compunction.
8. Poor judgment and failure to learn from experience.
9. Pathological egocentricity and incapacity to love.
10. General poverty in major affective reactions.
11. Specific loss of insight.
12. Unresponsiveness in general interpersonal relations.
13. Fantastic and uninviting behavior with drink, and sometimes without.
14. Suicide threats rarely carried out.
15. Sex life impersonal, trivial, and poorly integrated.
16. Failure to follow any life plan.

Psychopathy is in many cases also linked being a Sociopath, having Antisocial Personality Disorder, and Pseudopsychopathic Personality Disorder (also known as Frontal Lobe Disorder). The last of which is caused by lesions of the frontal lobe

Generally an intelligent, heterosexual, socially concerned male with adequate amounts of male hormone but who's sadly been hit with the ugly stick at birth. They go through most of their adolescents and young adulthood severley tormented, discriminated and rejected by both sexes because of personal appearance flaws, but its the female rejection which would later demonize them forever. Then from about ages 25+ these somewhat psychologically damaged and bitter individuals begin to despise all human rights and wrongs especially the 'asthetic law' which places the ugly away from the goodlooking. The end result being a sexually frustrated, deprived lonely individual whos only en-route to eden and out of depression is to go on a ballistic rampage for nothing more than self gratifcation, revenge and power.

A person who makes his own rules and lives in his own world. When you see this kind of person it is maditory to point that man or woman to the public so they know what they are dealing with.

similar to sociopath/antisocial personality but less emphasis on conning, manipulation and more on antisocial behaviors and often displaying the following traits

1...... extremely volatile personality with a long violent history and lack of regard for others. although sociopaths can be violent and often mad when their expectations are not met, psychopaths are more intrinsically violent
2..... impulsive and wreckless antisocial behaviors (ex: forcible rape, violent kidnappings and robberies, dangerous behaviors.
3..... dangerous behaviors stemming from a combination of personality disorders and mental illnesses yielding ane extremely dangerous type of offender
4..... MOST IMPORTANTLY: PREDATORY BEHAVIOR. The psychopath will enjoy hurting and killing others, they may even recieve sexual gratificaiton from such behaviors. They will often PREY ON OTHERS and never feel attached to others or bond to people.
