How can I appear more empathetical?

Knowing one sociopath doesn't mean every sociopath (if that's what he even is) is immediately like your brother, it'd be like if I got cheated on by a girl and came to the conclusion that all girls cheat, and what exactly does OP gain from trying to get sympathy? He isn't going to find a soulmate from this, or get financial support, the only thing he gain from this is advice, which is what he came here looking for, I don't see what he has to gain from 'manipulating' us.
Edit: Also read the original post again, OP says the baby dying made him unhappy, however he was unable to express it so it looked like he didn't give a ****

Has anyone in this thread bothered to take into account that Psychopathy or Sociopathy is not an actual diagnose used within psychiatry? Additional to that, diagnosing someone with -anything- without being educated, licensed and having observed the patient over an extended period of time is impossible and unethical.

There are literally hundreds of reason to why a person can experience little or no empathy, and not all of them are permanent.

To the owner of the thread: See a psychiatrist if you want to find out more about yourself. Your job is safe, anything said between you and your licensed psychiatrist is confidential. If you just want to -appear- more empathic I suggest you study how other people react to things, and then just practice your acting skills. And like you said - It's not likely that you'll turn into the next Ted Bundy.

... Unless you are a pathologically cold, respectless and manipulative person suffering from a serious inferiority complex stemming from a dysfunctional childhood and relationship to your family, and the suffering of a traumatic episode in which your ego was seriously damaged. Put simply of course. =)

Just like you said, author did express that he feels something but that part of the problem seems to be expressing it.

This is one of the most significant traits found within the Schizoid Personality Disorder found both within the ICD-10 and the DSM. Though it should still be said having traits found within a personality disorder does not at all mean that you have a personality disorder. To be diagnosed with a PD you need a number of these traits to be the very definition of your character, e.g. a pathology that manifests not only in actions but in mental and social function.

I agree that you should need more than a lack of empathy to be considered a PD. Yes, I feel "something", I'm not completely void of empathy. I know that torturing people is wrong for example and bad but I just don't care much for when it happens to people.

Isn't Schizoid quite similar to Asperger's? The PDs I noticed are just one big cluster of traits... Are all psychopaths even that charming? Jeffrey Dahmer didn't come across as a charmer to me.

Sheldon?

Schizoid PD is part of the Schizophrenic "spectrum" and shares a few characteristics with Aspergers. Aspergers however is part of the Autism spectrum and had no connection with Schizoid. Typical for Schizoid is that the person is rational in throught and has difficulties in expressing emotion. People apprehend the schizoid person as cold because the person does not convey emotion in ways that are noticable. Schizoid people are also often very straight forward and honest, a trait that is often misinterpreted as cruelty. Because of these things schizoid's are often misunderstood and people like to label them psychopathic or narcissistic without understanding how the schizoid person reasons. This inability to share emotional intimacy makes it difficult for schizoid's to form relationships based on pure emotion, but rather connections are established through other common factors. However the manipulative and deceptive behavior often observed in Psychopathy/Dissocial PD, and the impulsiveness and cruelty associated with ASPD are often missing.

Interesting you bring up Dahmer - He was not officially diagnosed to my knowledge. Looking at his history though one can clearly see the pathology of a serial killer in the making, but a psychopath not so much. His behavior was often erratic and of a very sexual nature, this teamed with his early developed alcoholism are very atypical of the cold and disciplinary psychopath. There was of course that incident where he convinced the police to release his 13-yearold victim into his custody, but that was probably more due to neglect on the police's part than a display of his manipulative prowess. I'd say (based on what I know alone) that Dahmer was a disorganised sexual sadist suffering from extreme abandonment issues (common within cannibalism/necrophilia) and delusions, but not a psychopath.
All psychopaths are not "charming" as charming is a trait which suggests the person is sincere and inviting. Someone manipulating others are quite the opposite, cold and using our will to connect against us for the purpose of personal gain. Manipulation is one of the traits listed in the Psychopathy checklist, but one doesn't have to tick all the boxes to qualify as a Psychopath according to the tests, 35 out of 60 if I remember correctly. So it's not -always-, just rather common =)

Asperger's?
