The relevance of the research topic is due to the fact that, being an integral part of the spiritual culture of society, Law and morality are inextricably linked. The history of the development of civilization confirms that the legal system of any state establishes important moral requirements for society. When developing or improving legal norms, the legislator must take into account the state of public moral culture for the fair adoption of laws and public support. The purpose of the research is the theoretical development of a set of criminal law issues related to the definition of the role of morality in the system of objects of criminal law protection, its place in the fight against crime, as well as the development of proposals to improve legislation regulating responsibility for crimes against public morality. The methodological basis of the research is: generally recognized methods of scientific analysis (systematic, comparative legal, formal legal, historical), as well as empirical methods such as statistical analysis, survey, study of documents and printed publications. The basic principles of the theory of criminal law, ethics, philosophy, psychology and logic are applied. It has been established that most crimes are committed intentionally. Examples include engaging in prostitution, bullying, or bullying pets. These crimes are committed for profit or for hooligan motives. The presented proposals are aimed at improving the legal regulation of these issues, which increases the importance of the study.
