Spoilers; while the could be an interesting twist or theme, there isn't. It's simply a case study where you go into it with all the information and come out of it vindicated. I was really hoping that at the end we'd find out it was all in her head and she was the "villain" but no such twist, no new information to bring closure. Even a cop-out reasoning of "idk, just killed ppl". His earlier explanation of wanting purpose was better. It was entertaining and free but cannot recommend.
