Define what actions are crimes and how to punish those who commit them. Criminal law is the body of law that relates to crime.
It prescribes behaviors perceived as threatening, harmful, or endangering people's property, health, safety, and moral well-being, including oneself.

The purpose of the criminal justice system is to protect society, punish offenders and rehabilitate offenders.
It does so by following a process in which the offender is arrested and tried for what he did wrong. If they are found guilty, they are punished in some way. There are important differences between the criminal law of most English-speaking countries and that of other countries. In this way, the importance of mens rea has been reduced in some areas of criminal law, but it obviously remains an important part of the criminal system.
Criminal law aims to identify, recognize, punish and educate the community in general and potential offenders about the consequences of their actions through the criminal justice system. The purpose of criminal sanctions was to make the offender repay the harm caused and to atone for his moral guilt; the punishment should be imposed in proportion to the guilt of the accused. In the United States, a Model Penal Code proposed by the American Law Institute in 1962 states that one of the objectives of criminal law should be to “warn fairly about the nature of conduct declared to constitute a crime” and “to promote the correction and rehabilitation of offenders.” United States criminal law, derived from English common law, has been adapted in some respects to American conditions. Criminal law, the body of laws that defines criminal offenses, regulates the arrest, prosecution and trial of suspected persons, and establishes the penalties and methods of treatment applicable to convicted offenders.
In some states and in the federal criminal code, so-called criminal codes are simply collections of individual provisions with little effort to relate the parts to the whole or to define or implement any theory of control through criminal measures. Northwest offers a flexible blended program with all criminal justice classes, Las Vegas law classes taught on campus by an attorney, and general education courses offered online. However, some Commonwealth countries, especially India, have enacted criminal codes that are based on English common criminal law. Criminal law is just one of the devices by which organized societies protect the security of individual interests and guarantee the survival of the group.
Strict liability can be described as criminal or civil liability, despite the lack of mens rea or intent on the part of the accused.
