Adultery is extramarital sex that is considered objectionable on social, religious, moral, or legal grounds. Although the sexual activities that constitute adultery vary, as well as the social, religious, and legal consequences, the concept exists in many cultures and shares some similarities in Christianity, Judaism and Islam. Adultery is viewed by many jurisdictions as offensive to public morals, undermining the marriage relationship.

Capital punishment, also known as the death penalty and formerly called judicial homicide, is the state-sanctioned practice of killing a person as a punishment for a crime, usually following an authorised, rule-governed process to conclude that the person is responsible for violating norms that warrant said punishment. The sentence ordering that an offender be punished in such a manner is known as a death sentence, and the act of carrying out the sentence is known as an execution. A prisoner who has been sentenced to death and awaits execution is condemned and is commonly referred to as being "on death row". Etymologically, the term capital refers to execution by beheading, but executions are carried out by many methods, including hanging, shooting, lethal injection, stoning, electrocution, and gassing.
