A question that is simpler to answer is whether or not her behavior matches that of a sociopath.
Of course, if the answer is yes, and I think that it is, then you have to ask what boundaries does a sociopath have to cross to become truly "evil". I'm willing to admit that some sociopaths are not evil, but when a person has 40,000 victims and not only taints evidence but makes up fantastic job titles and passes herself off as an expert witness in court, I think she may have crossed the threshold.
