The main problem is the relevance of the research topic. The history of the development of civilization shows that law and morality as components of the spiritual culture of society are organically linked to each other. The legal system of any state enshrines the moral requirements and moral principles that are vital for the whole society. When creating norms or improving them, the legislator must take into account the state of the public moral culture of the population so that the laws being developed are fair and perceived by members of society. Purpose: The purpose of the study is the further theoretical development of a set of criminal law issues related to determining the place of morality in the system of objects of criminal law protection, their role in the system of measures to combat crime, as well as the development on this basis of proposals and recommendations for improving criminal legislation regulating liability for attacks on public morality. Methods: Methodology and methodology of the study. The methodological basis of the study was made up of: generally recognized methods of scientific research of the phenomena of reality in their interrelation and interdependence both at the theoretical level (systemic, comparative legal, formal legal, historical methods of analysis, etc.) and at the empirical level (statistical analysis, questionnaires, research of documents, printed publications); the main provisions of the theory of criminal law, ethics, philosophy, psychology; rules of formal logic. The results and their significance: The stated circumstances, as well as the lack of elaboration and discussion of most of the provisions related to the modern legal regulation of crimes against public morality and their qualifications, determined the choice of the research topic. Crimes against morality are mostly committed intentionally. For example, involvement in prostitution, the organization of brothels for prostitution or maintenance, as well as other types of criminal acts directed against humanity (morality), are committed with direct intent. A person who organizes and maintains brothels for prostitution is aware that he is doing this for profit. Among the crimes committed against humanity (morality), animal abuse is committed mainly out of hooligan motives.
