: “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. Alternately you light up a Christmas tree!
Money is energy. You can hire a hit man with your cash and have someone killed… or you can put a kid through college.
So no. I don’t think you can look at a chart and have the expectation a person is going to be a nasty piece of work and you can see examples of this all over the place. There are plenty of good people, with bad charts and vice versa. We have free will!
