Human sacrifice
Human sacrifice may be a ritual practiced in a stable society, and may even be conducive to enhance societal unity (see: Sociology of religion), both by creating a bond unifying the sacrificing community, and in combining human sacrifice and capital punishment, by removing individuals that have a negative effect on societal stability (criminals, religious heretics, foreign slaves or prisoners of war). However, outside of civil religion, human sacrifice may also result in outbursts of blood frenzy and mass killings that destabilize society. The bursts of society-sanctioned killings during European witch-hunts, or during the French Revolutionary Reign of Terror, may show similar sociological patterns (see also Moral panic).
