The clown killer John Wayne Gacy is also Pisces Sun, Moon & Mercury.
scarey stuff!
Pisces is really a very weak sign (they say), esp. if it's Saturn, (lack of self-discipline), or Mars (inconsistent goals), or Mercury (decreased confidence)
I've found women especially with Venus in Pisces tend to sacrifice themselves, to the point where they lose their own self in others.,not at all a good thing.
But then again, how many of us can resonate to the Christ or Jesus Pisces? very few, but he was one, if Cayce's time of birth is correct, having his Sun at 28Pisces and even Venus in Pisces 24 deg. the ultimate Sacrifice
