Who was the last murderer in the movie "Door Lock"?

To put it simply, the murderer is a psychopath with childhood trauma. This kind of answer makes many viewers not satisfied. But this undoubtedly echoes a frightening fact in real life mentioned above-it is difficult for us to predict the motive of the murderer. He can use violence because of "love" in his logic (Dr. Zheng thinks he loves Fang Hui, and his behavior is to protect and love her), or he can use violence because of "no love" in his logic (Dr. Zheng kidnapped Qiao Xiaoman because he thought she was "too noisy" to stop him from being with Fang Hui).

At the end of the film, Fang Hui and Qiao Xiaoman sit in a car and drive forward in the sun. They always care about each other, never give up, live alone, and finally save each other. The rescue of the police also gave the hostess a full sense of security! The subtitles at the end of the film tell the audience that there are a large number of women living alone, reminding the audience to pay attention to this problem again, connecting the film with reality and giving us the answer of social concern.
