Interesting video from PBS, circa 2012. Inter species relationships. Watching the animals care for each other seems hauntingly compassionate. Perhaps perceptively contradictory to the nature of psychopaths.
In this episode the relationships all have something in common. The relationships between animals are initiated and subsidized by empathic humans. Perhaps there are clues within cross species partnerships to better relationships between emaths and psychopaths, for both parties. You might want to look at the sponsored sociopathy post for a human specific analysis.
