What was Blanchett's motivation?
I enjoyed the film for the most part, but was left with one nagging question: What motivated the psychiatrist, Dr. Ritter (Cate Blanchett) to go to such lengths just to destroy the life of some phony entertainer she had no prior relationship with?
During their final confrontation where it's revealed she's been setting Stanton up, the doctor specifically acknowledges that she never cared about the money gained through their collusion. Rather, it seemed she just had some extreme vendetta against him. She disliked like him for being an arrogant scam artist, calling him a "small, small man" who considered himself better than everyone else.
But was that enough to justify her actions? Not only ruining Stanton, but causing so much additional suffering in the process, including the deaths of several other people (some of them completely innocent).
I figured there had to be more to it; like perhaps the psychiatrist was someone from Stanton's past he had caused great harm, but no. As far as I could tell, she just considered him to be a pompous fraud. Which seems like a rather weak reason to set her utterly diabolical plot into motion.
Did I miss something?
