Eye for an eye
"An eye for an eye" (Biblical Hebrew: עַ֚יִן תַּ֣חַת עַ֔יִן‎) or the law of retaliation (Latin: lex talionis) is the principle that a person who has injured another person is to be penalized to a similar degree, and the person inflicting such punishment should be the injured party. In softer interpretations, it means the victim receives the [estimated] value of the injury in compensation. The intent behind the principle was to restrict compensation to the value of the loss.
