It is fascinating that Moon and/or Venus often play a dominant role in charts of people whom we consider as psychopaths. In fact, the charts of a lot of allegedly "unfeeling" and "cold-blooded" psychopaths have an emphasis of the water element. Surprising?
From a psychological point of view it becomes clear that these people have often had difficulties to cope with their strong sensitivity and emotions in their past. They found it easier to lock their feelings away and keep them 'water-tight' so that they didn't have to feel them. But they have found other outlets for their watery side: they use their strong capacity for empathy to 'slip into their victims' skin' and find out about their weaknesses and fears in order to exploit them ruthlessly. To the psychopath it may "only" feel like striking back, like a revenge for their own hurt feelings...
