Criminals are individuals who engage in illegal activities that violate laws set by society. These actions can range from minor offenses, like petty theft, to serious crimes, such as murder or fraud. Criminal behavior is often influenced by various factors, including social, economic, and psychological conditions. The legal system categorizes criminals based on the severity of their actions. Misdemeanors are less serious offenses, while felonies are more severe and can result in harsher penalties. Understanding the motivations and circumstances surrounding criminal behavior is essential for developing effective prevention and rehabilitation strategies.
