Zhangzhou man committed suicide after killing his father. What is his psychology?

This happened in Zhangzhou, Fujian. A 6-year-old man Wei Mou killed his 84-year-old father. This matter has been discussed on the internet. The 64-year-old man was very cruel when he killed his father. Moreover, the means are also very tyrannical, very horrible, and the scene is also very bloody, which makes people shudder when they think about it. From the police report, we can also see that it probably means that the police went to the scene to deal with it after receiving a report from their family. The case was because Wei had a conflict with his father because of some trivial things, and then killed his father with a gun in the early hours of the morning. Finally, his son Wei committed suicide. Because a certain behavior really makes people unable to understand. There are disputes and conflicts in the family, and then they kill people. Not only that, but also cut off his old father's hands and head and put them in a pressure cooker for cooking. This behavior is simply incomprehensible. What is the reason? Wei will put his head and hands nearby in a pressure cooker to cook. Now there is no way to know. However, after understanding, Wei is a person with extreme thoughts and often insults his parents. From this we can see that Wei is a very unfilial person, and he has a lot of dissatisfaction and resentment towards his parents. It is not clear where these dissatisfaction and resentment come from. However, Wei is 6 years old and has so much dissatisfaction and resentment. At this age, he should slowly let go, and Wei, 6, is an intellectual. At the age of 6, he still hasn't given up his resentment and dissatisfaction with his parents, which shows that his character is not good. At least his thought is very extreme, which can still be established. Extreme thinking, doing such a thing is really incomprehensible and unforgivable. This case has come to an end, but it makes people think a lot.
