Thank you Meg! I listened to it in the course of a few days. And indeed, she does seem very caring and normal now! I thought that the interviewer was TERRIBLE, but that Beth handled her quite well.
Given her background, I think it's understandable that she may view so many people as having attachment disorder, and not as born psychopaths. She doesn't say so herself, but it's what can be inferred when she mentions evil in this world. And for all we know, this is true, and a big percentage of "psychopaths" weren't really born that way. Dr. Frankenstein talks about it in his book Psychopathy, and about how those first years of life are crucial. There is nature, yes, but problems at birth and nurture contribute a lot to the particular outcome. And then, the inner strength or the life lessons of each individual, I guess. Beth could have not changed at all, for example, like many, many others.
