I am Pisces/Sun, Scorpio/Moon with Libra Rising and I often say if it wasn't for Libra I'd be in jail by now, lol. However there are other attributes (Jupiter/Pluto aspecting Scorpio Moon) that make me much more moody/possessive than the average so I believe it depends on the other factors in a chart. One very experienced astrologer told me once: "Pisces/Scorpios are not based in reality."
