: “Are there any aspects in a chart that make you leery that the native might use his powers for ill?”
I don’t think so. The chart shows a person’s energy and energy is neutral, until directed. You can think in terms of electricity. Electricity is energy, right? You can electrocute a human being with it, or alternately you light up a Christmas tree!
Money is energy. You can hire a hit man with your cash…have someone killed, or you can put a kid through college.
So no. As far as I am concerned, you cannot look at a chart and have the expectation a person is going to be a nasty piece of work…and examples abound. There are lots of very good people, with very bad charts, that is. And vice versa.
