She is a person who needs to feel better and more powerful than others, likes to be always right and in control, to the point it doesn’t matter if she hurts others to get what she wants. one of those ways is becoming a therapist, where she has power over her patients and most likely doesn’t even help them that much because she likes to be the top dog and, as we see in the movie, she is quite manipulative.

First sign of it, ad whole reason behind her actions, is how she publicly went to his shows to figure out his system, and then publicly challenged him to humiliate him and expose him as a fraud in front of everyone, not for justice but for herself to feel powerful. But what happened was that he won twice, once by tharting her plan of exposing him publicly but also by saying some very specific personal things in front of everyone. That’s why she did what she did, she felt so humiliated that decided to take vengance. In conclusion, she’s just a really bad person.
