Sociopaths in the news

On actress Anne Hathaway's ex, Italian businessman Raffaello Follieri:

When I advise women and men about how to avoid someone with sociopathic tendencies, I tell them don't expect a monster; instead expect someone oozing with charm. Yet, underneath the heat and charisma are cold thoughts and actions devoid of empathy. Impulsivity, thrill-seeking, and constant boredom are characteristic.
Relationships are used as stepping stones to get them where they want to go. They have an uncanny ability to push someone to the brink, but then suck them back into the relationship again. It's drama, and they love it.

But cads are not infallible. There are always signs. That's why it's so important to educate men and women to see the signs, as well as helping them achieve the courage and willingness it takes to interpret them.

I'm not sure exactly what the signs would be, possibly claiming a personal relationship with the Pope?
