Crime and Punishment (Murderer) What is the motive for framing Aaron Kwok's half-brother?

I just saw the film you mentioned. It's murder (Hong Kong version), not crime and punishment (Mainland version). So I can discuss it with you.

Psychopathy: I think it's the same as many movies except this one. Psychopathy is influenced in childhood, which has a lot to do with his growing background.

Motivation of the framework:

Factor 1: The younger brother in the film, to a great extent, lost his father's love because of his single parent, and his mother lacked correct guidance and care. Without love, his hatred is also caused by his father's lack. In the eyes of the child, as well as the ideological hints given to him by his mother, hatred comes from "the mother of Aaron Kwok and Aaron Kwok", and "Aaron Kwok" insulted him and beat him with words in childhood. This is a childhood.

Factor 2: Being sick all the year round is already a kind of psychological torture for the patient himself, not to mention the name of his demon from the outside world. He hates people saying that he is not tall, that he has been suffering psychologically, and that he has started to get sick psychologically and mentally. In addition, because he can't grow up like a normal person to earn money to support his family, he has been watching his mother engage in prostitution for his own life. Until his mother died of illness, all these sufferings that he had endured and should not have endured need to be answered, and someone needs to be responsible, that is, who made them like this and why he and his mother came to this step today. The answer is "Aaron Kwok and his mother"

Factor 3: Jealousy, Aaron Kwok will be promoted to supervisor in a month. In Hong Kong, a superintendent is a senior police officer. Superintendents usually have to hold leadership positions, such as the commander of a division, the director of a police district and the head of a department in that police district. Aaron Kwok's future is great, and his career reached such a peak at the age of 40. In life, Aaron Kwok lives in a villa with a sea view, so beautiful and considerate. The cars they drive are super tasteful Land Rover. When life is proud, I don't know what disappointment is. I didn't know he would have a younger brother who was inferior to a pig and a dog. He was also born by his father, but the gap between living in this world is unimaginable. Therefore, everything that "Aaron Kwok" has, he thinks, was originally his, or should be his. Perhaps without "Aaron Kwok", his childhood would not have suffered. If he is not in pain, he may not get sick. In his view, his mother doesn't have to engage in prostitution, he doesn't have to be laughed at as a monster, and he doesn't have to kidnap children with his conscience to survive. Aaron Kwok turned him into a demon, so he wanted to return what he had suffered to Aaron Kwok.
