A "Life Sentence" is a type of punishment given to individuals convicted of serious crimes, such as murder. It means that the person will spend the rest of their life in prison, without the possibility of parole, which is the chance to be released early. This sentence is intended to reflect the severity of the crime and to protect society from dangerous offenders. In some legal systems, a life sentence can vary in its specifics. For example, in the United States, some states allow for the possibility of parole after a certain number of years, while others do not. Additionally, a life sentence can sometimes be imposed for multiple offenses, leading to longer periods of incarceration.
