I don't think anyone expected her to decipher and stop Mark's plan. What I would expect is that, in her first interview, she would not say the marriage was a typical happy marriage, and then, in her second interview, admit the marriage was troubled but put all the blame on Teresa's alleged abusive upbringing, drug and sexual additions, alleged agitation of Mark, etc., etc., while never mentioning Mark's womanizing and other shortcomings. This seems as far from intuitive as one could possibly get; in fact it seems calculated to obscure Mark's guilt. Based on the LS interviews and the material on LS's own website, I'd go further, and say that Teresa's affiliation with LS was as big a mistake for her as her marriage to Mark, even if, as Sheriff Scott seems to assure us, LS had nothing to do with her murder. As a potential patient, I believe this was not an affiliation that would benefit any board certified MD, no matter how holistic.
