Ted Bundy was also a sociopath, but more typical of the male type in that he not only was indifferent to the pain of others, he actually enjoyed it. He was a sexual serial murderer, and Bishop is not...she is a mass murderer.
As is often the case when something like this happens... the stories start coming out of the woodwork.
That inability to feel empathy makes me wonder what kind of mother she has been to her 4 children? Mothering/nurturing almost always requires one to sacrifice and care about your children above yourself. She may have viewed them as little extensions of herself and considered their accomplishments to be her own.
Should I be worried that I find this so fascinating - LOL????
