A criminal is an individual who engages in illegal activities that violate laws established by society. These actions can range from minor offenses, such as petty theft, to serious crimes like robbery or murder. Criminals may operate alone or as part of a group, and their motivations can vary, including financial gain, revenge, or other personal reasons. The legal system categorizes criminals based on the severity of their actions. For example, felons are individuals convicted of serious crimes, while misdemeanants commit less severe offenses. The consequences for criminal behavior can include fines, community service, or imprisonment, depending on the nature of the crime.
