Human life is the most important social value protected by criminal law. The legal protection of life is an essential condition for the existence and proper functioning of society as a whole, but also of the family as the basic cell of society. Murder committed against a family member, with its variants, respectively simple murder and qualified murder, is one of the normative modalities of the crime of domestic violence, provided and punished by article 199 paragraph 1 of the Criminal Code. Family crimes are based on sexual motives, from the perspective of infidelity of spouses or concubines - jealousy and a strong desire for revenge cause the cheated spouse to suppress the life of the unfaithful spouse, often the murderous action is directed at a other people, the lover or boyfriend (girlfriend). Other causes of crimes committed in the family are egocentrism and uncontrollable pride of the aggressor, who wants to impose his supremacy over other family members, alcohol or psychoactive substances, but also major mental disorders such as schizophrenia or delusional disorders. Also, some patterns of household organization, but also some lifestyle habits, as well as the victimization of the minor child, can become stressors, generators of negative emotions, which ultimately lead to the killing of one or more family members. The victim also contributes to the criminal act through behavior and attitude - she is often guilty of the unfortunate finality of the acts of violence. The victim can be more guilty than the aggressor or even totally guilty, when she triggers the conflict, of course most of the time on the background of alcohol intoxication or with forbidden substances. The causes that influence victimization in the family are adultery, alcoholism, the existence of vices, behavioral rigidity, cohabitation, egocentrism and pride of the victim, but also impulsivity.
