To answer that, let's have a look the easiest difference: Ted was born a boy and Penny was born a girl. From the moment we are born, we are conditioned into being a boy or a girl. Everything about the manner in which we are spoken to, played with, or the people we are encouraged to interact with, encouraged into a career or the clothes we are given to wear are acts of conditioning. There is even a difference with astrology: for men, we tend to look at Mars and for girls, we tend to look at Venus (I just want to say I'm glad we're moving away from this tendency as a society. It has been a topic astrologers have talked about amongst themselves for quite some time). My point is, there are external forces that shape behaviour on the simplest level.
Let's take another easy difference: Penny grew up in a family who encouraged her to read and create stories as she was learning to read and write. By contrast, Ted grew up in an odd household with a violent father and severely depressed mother--and just about the time of his second Jupiter return, he discovered these parents were in fact his grandparents. His "sister" was his true mother and the identity of his biological father never known.
The next question might be around serial killer profiling: there are not many--if any at all--serial killers whose immediate family went to such great lengths to maintain a total lie about a child's basic identity. But then it is not known how many serial killers had the same astrological significators such Jupiter in Scorpio square natal Saturn/Pluto, that would have been triggered in same way as Ted's. This is yet another reason why I don't think you can just look at a birth chart and make a judgment about someone's free will: one HAS to look at the Jupiter and Saturn transits.
By the time of their Jupiter return, both Ted and Penny would be settled into the careers that would make them famous.. As Jupiter is in Scorpio for both, it would be interesting to look at the description for this. Although I wrote this for the first Jupiter return, the same premises would be in operation for the second Jupiter return:
"Secondary school offers these pupils a chance to become involved in every drama going on. Scratch the surface of some commotion, and you’re likely to find they have been involved somehow. For the next drama, you’ll have to scratch even deeper because they are learning the art of evasion. Eventually, you’ll find no trace of their involvement because they’ve set someone else up to be the fall guy. On the flip side, there will inevitably be pupils who are terrified of their own power. They are frightened of change because they have learned that where there is gain, there is a loss attached. Someone they love dies and they inherit money, they meet the love of their life but endure years of abuse (both given and received) or they indulge in their occult fantasies only to be sucked into the abyss. They love mysteries, “unsolvable” puzzles and, pointed in the right direction, they love to research. "
Both Ted and Penny were active in the respective fields from 1974-1978. The majority of his known killings took place in these years and she was writing books that would be published (all at once) in 1979. He was on trial in 1979. Both author and killer were known--in different ways--for their shape shifting abilities by the time they reached prominence. He had a "generic" style that made it difficult for victims to identify distinguishing features. She used several pseudonyms that served different purposes throughout her writing career. Astrologically what was happening for them in 1979 was that Jupiter was transiting their natal Saturn whilst Uranus was transiting their natal planets in Scorpio.
He was executed on 24 Jan 1989 as Pluto transited his natal stellium in Scorpio. She died on 31 December 2011 as Jupiter opposed their natal Chiron.
But what I find most interesting is that for Ted Bundy, "possession", a Scorpio keyword, was a factor in his motivation to rape, murder and violate after death. And Penny Jordan used the same trait "possession" that is) to describe the "Alpha male" love interests in her novels. She even wrote a book called "Passionate Possessions" as Transit Pluto transited their natal Sun half a Jupiter cycle after he was executed in the electric chair. Whilst not going to the same extremes as Ted, just the titles of her books indicates she has simply re-directed the same themes in a different manner. Other titles of her books include: "The Hard Man", "A Forbidden Loving" and "Power Games". And by the way, I think the man on the front cover of her novel "Power Games" with the tagline of "Power over life, love. ..and death" could bear more than just a passing resemblance to Ted Bundy.
