Understanding Antisocial Personality Disorders

The following excerpt was taken from a comment found on a YouTube video about sociopathy.  This comment gives insight regarding the inner reality of someone with antisocial personality disorder.

You're right in some points, but frankly, I'm a sociopath and/or psychopath (went to several psychologists and was diagnosed), and it irks me that you speak about sociopaths like they are only out to get you, which is wrong. Yes, I don't care at all about you, and I will lie, cheat, and manipulate you until I get what I want, but I only do it if the gain is worth it as I'm aware that people won't trust me if I swindle all I meet. Unless it's worth the risk of losing all my hard work of gaining trust, I don't do it (lie, cheat, and manipulate) unless I know I'll get away with it. The friends part, also, isn't too accurate. Yes, I don't care about my friends, but I'm less likely to (lie, cheat, and manipulate) because I need social interaction. Having no friends drives me mad with boredom, not like they don't bore me already, but it's not half as bad as isolation. Also, you talk about sociopaths like they're all murderers, which is wrong. The lack of empathy makes jobs like surgeons, lawyers, and soldiers a sinch as we don't have remorse about what we do and are steady. Now the manipulating emotions for benefit isn't always true, since I usually manipulate emotions of people for the reaction. I get bored and nothing makes me happier than to see the convulsing face of an angry person. All that other shit was pretty accurate I suppose, but I suggest not talking like sociopaths are always out for blood.

Because people with antisocial personality disorder don't care about other people or have empathy, they are really only out to meet their own needs and use other people to do so.

Expecting them to be honest and trustworthy is a mistake.

Sometimes they tell the truth and sometimes they lie, which makes it very difficult to know when to believe them.

For people with empathy, attempting an intimate relationship with these people is fraught with pain.

Learning how to identify people with antisocial personality is essential to know how to relate, and how not to relate, to them. 

Smart sociopaths probably know they are different from most people.  They recognize that they don't have feelings of empathy and likely think most people are burdened with those feelings. They are glad they don't have empathy and see it as a problem.  But to meet their needs, which is all they really care about, they learn to act with empathy in order to manipulate others.  They become very good at pretending.  Acting charming and charismatic is another way for them to gain power over others.
