Is it possible to not have a conscience?

“Sociopath” is a term people use, often arbitrarily, to describe someone who is apparently without conscience. While the characteristics of sociopathy and psychopathy may overlap, sociopathy is the unofficial term for antisocial personality disorder (APD).

Why to have sociopaths failed to develop a conscience?

Specifically, sociopaths lack conscience because they are unable to experience guilt and empathy. To understand how sociopathy develops, we must understand how guilt and empathy develop. Scientists have begun to understand how guilt develops in children.

Do sociopaths have any emotions?

Sociopaths don’t have feelings or emotions, nor do sociopaths cry genuinely. However, they do experience proto-emotions, primitive emotions that rear their ugly heads in moments of perceived need.

Can a person stop being a sociopath?

Stop being a sociopath will be very difficult. Stop acting like one though, is more realistic. If someone developed to be a sociopath, his/her conscience has not developed.

Do sociopaths know that they are sociopaths?

The short answer is yes, sociopaths are generally aware that they are sociopaths. This is one of the differences between sociopaths and narcissists. Sociopaths know they are different from other people, but can force themselves to think and act like a neurotypical person.
