Hi Jen!
For the past few days I've been collecting birth charts of people of known psychological structures to see if I can find the common astrological aspects that would indicate them. So I was very happy to bump into this thread and readily registered.
The first thing we have to say is that the way we relate to people depends on how we deal with our inner demons more than the nature of the demons themselves. For example, not every man with a harsh Mars-Saturn aspect (present in your sociopathic person's chart) will deal with it with cruelty towards others, but it happens in many cases (the Marquis of Sade, "inventor" of sadism, had a Mars-Saturn square). This is because his masculine ego and drive, represented by Mars, is being repressed by Saturn, creating an enormous inner anger and tension. One can either sumbit to his Super-Ego (Saturn) and not be assertive at all, or one can send it to hell and become overly assertive to the point of being reckless and cruel if need be (like the person you were talking about).
In your "friend"'s case, his Mars is further tormented by the square to Neptune (planet of dreams, illusions, spirituality,...), giving an unnatainable feeling of one's drives. And if this wasn't enough, he has Mars opposition Jupiter, which is an indicator of narcisim, for Jupiter in a harsh aspect always exagerates things and over-expresses them. So considering only Mars in the guy's chart, I would say he has a huge unconscious feeling of impotence towards his masculine ego, which he compensates by being harsh, reckless, violent and cruel towards others.
This impotence is further stressed by a 7th house Pluto (if he was born at 1:30 like you suggested). Pluto is associated to power and anything that falls in your seventh house is somewhat unconscious which you need to reach within yourself in order to feel "whole", but many don't and jusk seek it in a partner, living it through projection. So with all these influences, I bet this guy can't get an erection with a woman unless he totally dominates her. But I'll say it again, not everyone with these aspects will behave like this. This is obviously someone who has taken the easy way out, taking advantage of others to feel powerful instead of facing his own demons. I bet his parents didn't let him do anything he wanted when he was a kid or severely punished him when he did.
Looking at others things, I can tell you I have found your sociopaths Sun-Uranus harsh aspect in most other sociopathic people's charts. This means one's Ego's structure is not very stable and most people with this aspect are very selfish. This influence is an indicator of a Borderline Ego structure and this structure is associated with an inner feeling of emptiness and deep insecurities (but not everyone with this aspect is borderline ok). Everybody with this structure is extremely intense although some may hide it with a high degree of control. These people possess a defensive mechanism called splitting, which make them feel everything either extremely good or extremely bad with no midpoint. So they have a high degree of idealization, but if they see you as the bad object, they will show no mercy. Some Borderline structures, when not organized, have little space for the feelings of others. They can hurt you and not feel anything by it. While a psychotic structure will fantasy how others are and feel (therefore being sensitive to other's feelings), the borderline just doesn't feel the other (hence the inner emptiness he has). The borderline unconsciously tries to apprehend the feeling of others by testing them and attacking them constantly (not necessarily in a harmful way). You know those people who like to **** you off and feel somewhat relieved when you calmly assert yourself and create boundaries, stopping their omnipotence? That actually makes them feel safe, even if they get angry after you do that. And they'll respect you for it and love you more.
Ok I'm overextending myself... I'll say one last thing about the chart: I agree with what Frisiangal said about the Moon-Mercury conjunction in Gemini. He will be extremely rational about his emotions. Thought will dominate over feeling. And the fact that there are no personal planets in a water sign could be the sign of lack of empathy. Oh and Mercury making a square to pluto can bring about mental manipulation. The guy is certainly extremely intelligent.
Sorry for the huge thread. Hope that was helpful. Best wishes!
PS: can we have the wife's date of birth?
He might therefore take out his suppressed anger on the opposite sex.
