Respectfully BBM: Mental illness and personality disorders are two completely different conditions. There is no treatment or cure for what ails Jodi Arias. Her mother made the statement that she is bi-polar. Obviously Dr. Demarte thought otherwise. Jodi Arias is a dangerous psychopath/sociopath, and needs to be kept away from the rest of society so she never harms another human being. No treatment exists that would make that otherwise. Think about Ted Bundy...would he have benefitted from any kind of treatment?
There are psychopaths/sociopaths who can function within society, but I don't believe Jodi Arias is one of them. MOO. But I do agree with you that she, and she alone, is responsible for her actions.
