When a person is suffering from Multiple Personality Disorder or formally known as Dissociative Identity Disorder (aka:DID) the attributes of their personalities may vary in interactivity with other personalities, and frequency that a particular personality is active. Some DIDs experience the appearance of new personalities, particularly under stress. This brings up an interesting question. Is there a risk that a DID can spontaneously spawn a personality that is a psychopath?
In a model where a particular physical part of the brain is associated with the conscience the answer is definitively yes. A new personality that was physically isolated from lets say the amygdala, and previous personalities, would not be able to form empathy. If their isolation did not change that personality could stay a psychopath indefinitely.
While data is spotty, it seems to me if the conscience were an isolated organ of the brain, there would be many more crimes committed by newly split multiple personalities. Usually personalities share knowledge, and take up specific areas of the brain as identified by MRI. If this were the case why wouldn’t a psychopathic personality, isolated from key parts of the brain, form every time a DID first fractured? If a psychopathic personally formed nearly every time or even sometimes, wouldn’t it immediately seek retribution against those who harmed it?
In the metamind model behaviour is more consistent with early DID behaviour. First the bad news. All empaths are born as effective psychopaths as infants and their metamind is fully active by the time they are about 7 years old. So a brand new personality could ethically be an infant and effectively a psychopath. The new personality would likely speak very simply if at all and be very physically oriented.
The good news is, they would also be a narcissist and very inward looking, if not threatened or otherwise goaded into confrontation with the outside world. This would improve over time as their isolated metamind collected emotional data. If enough time passed for the new personality in a safe environment, it could be as conscionable as any other empath. A safe environment may not be possible or likely though, as the new personality may only appear under stressful conditions.
If you are a DID and are going to attempt to reach a new, isolated, possibly psychopathic personality, you should try to reach them with a passive gentle minded personality, not an aggressive one. Narcissists isolate themselves intentionally for protection from a world they don’t understand, and reaching them with an aggressive approach will garner an aggressive life or death response, known as narcissist rage.
Please if you are suffering from DID seek a therapist who specialises in DID cases, especially if you think an isolated personality may be psychopathic!
