If you've never had close dealings with a narcopath, you won't understand the damage they can do. This disbelief factor is what allows them to get away with so much. By now, most people know that sociopaths exist. However, it's assumed people with this extreme moral disorder, are serving time in jail, or will be, as soon as they're caught. Less plausible is the fact that high functioning sociopaths (narcopaths) are working as doctors, lawyers, accountants and teachers. You even find them in ministry. Sometimes, you'll find them praying in the pews.
Narcopaths are our next-door neighbors. Or, the "nice" young mother driving her children around town may have a deeply disturbed and malignant personality.
Once you have a run in with a narcopath which typically results in your life being turned upside down, at least temporarily, you know they exist. What we need is a whole new level of awareness, so these sneaky, character-flawed people don't get away with quite so much.
