what is the best way to get back at a sociopath
By all means be polite and civil to a sociopath, but avoid a close relationship. Sociopaths want victims and are incapable of love. They can be very destructive, and a close relationship with a sociopath is often a very damaging experience.
It is possible. Sociopaths have no sense of boundaries or guilt.
you may want to rephrase this question a bit more clearly... What exactly are you asking>
The sociopath lacked empathy and manipulated others for personal gain.
A good actor. Though you cannot be sure if they are truly a sociopath or not until they have been diagnosed as such. If they honestly care about people then I would look along the narcissistic route. If they are a sociopath, then the caring is most likely an act so that they can get what they want.
If the sociopath thinks he can bleed more out of you than his wife, that's all it will take. Sociopaths have no interest in what you want, only in what they can get. By definition they have no conscience or respect for other people's feelings, and the condition is untreatable. The important question is, what is wrong with YOU that you desire a relationship with a sociopath?
It is the place that the sociopath wants you in, they want you to rely on them, to care so much that you will do anything. To cater to their every need. They enjoy the power of being one who can control others.
A sociopath is a person who has no concept nor concern of the consequences of their actions on society in general. If you are afraid of this person, don't cheat just leave. Why would you want to put yourself in a dangerous position.
You don't. Get as far away from a sociopath as you possibly can.
Yes, but both would not like it, and it would probably not last. Living with a sociopath is awful for anybody, and the main reason that people stay is because they don't want to hurt the sociopath. As a sociopath is egocentric, the sociopaths would not care about each other's feelings, and would leave each other.
