ITA and I believe so do most experts. I'm no psychiatrist, but it seems pretty obvious that TLM is a psychopath. The nuking of her dog as a child is typical behavior for one, and then there are her gruesome fantasies of torture and murder, as well as her actual crimes. I have to wonder what other horrific deeds she has committed that no one even knows about. IMHO there is no way to change the way these people think, scheme, and act.
But I think what the poster meant by "rehabilitation" in this case was that it's possible that TLM might eventually become the type of model prisoner who may get transferred to a less secure institution at some point. Judging by her attack on a fellow inmate as recently as this January, I have serious doubts.
