"Blood Money"
Blood money, also called bloodwit, is money or some sort of compensation paid by an offender (usually a murderer) or their family group to the family or kin group of the victim.
These fines completely protect the offender (or the kinsfolk thereof) from the vengeance of the injured family.
In Judaism, since a person's life is considered to be the property of God, the taking of blood-money for the life of a murdered victim is forbidden.
