Analyze the definition of criminal motives from the perspective of "Criminal Psychology": According to the definition of mainland criminal law textbooks, the so-called criminal motive refers to the inner cause or ideological activity that stimulates and prompts the offender to commit a criminal act, which answers the question of what psychological reasons the offender commits the criminal act, so the role of the motive is to launch the criminal act; it shows what the significance of the psychological desire to commit the criminal act is. Today, without analyzing the murder of Aunt Kaifeng, I will introduce to netizens the general criminal motives for killing criminals. Simply put, it is the cause of the vendetta

Definition of the motive for the crime
A, family conflicts (both love killing and vendetta killing)
Most of the motives for this kind of crime are the accumulated resentment caused by the rift in the feelings of husband and wife, and the contradiction is not a case of hatred that can accumulate deep hatred in one day or two days. Here I will mainly talk about the types of vendettas that arise from family conflicts. a, because of love and hate: This is because one of the spouses loves the other deeply, but the other party cheats outside the marriage and family and is found to be adulterous. Thus betraying the beloved to him, he felt that he had wrongly paid to truly love her. In this way, he takes revenge on the cheater and the person who wears the green hat on himself, thus being carried away by hatred and venting his anger at the betrayer of his lover and the murder of the person who wears the green hat. b, one of the spouses has the phenomenon of domestic violence, and most of the domestic violence is male, in the case of domestic violence. Because male domestic violence is generally very cruel, the physical and mental destruction of women is very painful. At this time, women can't stand long-term domestic violence, and over time they will have hatred for the domestic violence party, and then they will have thoughts and actions to kill him. C, the relationship between husband and wife has long been in the contradiction of Ah Ke's reconciliation, such as some contradictions in marriage and family life have not been resolved in time, and over time there will be great contradictions. At this time, one party feels that the other party brings great trouble to itself, such as the husband and wife who have been in the point of contradiction and conflict for a long time due to a momentary impulse, resulting in passionate vendetta and killing, but also with the component of love killing.
Feuds resulting from family conflicts
B. Social interaction occurs with hatred arising from the direct interests of others
Most of the motives for such crimes are hatred caused by the victims in their social interactions, and the direct interests of the other party are damaged by the entanglement of interests between friends. However, it must be that the more serious economic interests are encroached upon, and the other party has hatred for the usurpation of his interests, and finally kills the other party because of the economic damage. a, because of money or debt. 1, money will have the idea of chasing anyone, as the saying goes, "people do not perish for their own sake" is this truth. The world began to have money from the day it existed, and the pursuit of money by human beings has always been a dream. Sometimes friends will fight each other for money, and even because of some things about money, hatred will arise, thus killing each other for the benefit of money. 2, debt relationship sometimes some people lend to each other usurers, netizens know that the interest rate of usury is super high or even astronomical. The borrower will most likely have no money to repay the loan, and the borrower will use force to repay the money, and the person who cannot repay the loan will hate and kill the borrower.
Finally, there is a special case (because a friend's wife cannot be deceived), and vice versa, because a friend's wife is beautiful like a flower. Some people will be tempted to tease a friend's wife, and then the friend's wife can't stand the provocation and hook up into adultery. In the end, they are found by their friends to take revenge on them, and as a result, they kill their friends who picked up their wives and kill them together with their wives to vent their hatred.
Fight for power and profit, and fight for family property after the death of parents
C, the struggle for power and profit, the death of parents to compete for family property
This criminal motive can be roughly divided into two situations: the first is because of the promotion and wealth in the unit, and the mutual exclusion of colleagues due to the slander and slander of comrades. The second is that after the death of the parents, there is a lot of family property, and hatred arises between brothers and sisters, and sometimes one of them kills his brothers and sisters in a momentary excitement, which kills one or more people.
In summary, there are many qualitative classifications of vendettas mentioned above, and the main thing is that the judicial organs investigate through the scene of the crime. Thus collecting various evidence at the scene of the crime, and then analyzing the physical evidence and testimony collected, from which the method of committing the crime was found, the conclusion was drawn, and finally the case was characterized according to the situation obtained. In general, it is nothing more than love killing, vendetta killing, love killing and vendetta killing at the same time, in fact, there are many case characterizations that are not listed here.
