One of the problems with dealing with unattached people or sociopaths is the difficulty of recognition. At one time, they seem friendly, intelligent, well adjusted, and exhibit apparent sincerity in wanting to be a friend to others. At other times, their behavior seems to snap over, instantaneously, to that of a selfish ten year old. In Kohlberg's view of moral decision making, the age of ten is when a person begins to use the Everyone Rule (what would the world be like if everyone did the action in question). Sociopaths often do not consider others, rather seek instantaneous gratification of their own impulsive needs, much like a ten year old.
Sociopaths are often superficially charming, yet frequently exhibit certain adverse character traits. They are:
untrustworthy vs trustworthy
disloyal vs. loyal
selfish vs. helpful
unfriendly vs. friendly
discourteous vs. courteous (polite)
mean vs. kind
rebellious vs. obedient (a team player)
wasteful vs. thrifty
