Eye for an eye, a tooth for a tooth

The phrase eye for an eye, a tooth for a tooth refers to a principle found in Babylonian Law, in the Code of Hammurabi, as well as in monotheist religions - Judaism, Christianity and Islam. According to this principle a person who has injured another person is penalized to a similar degree.

Example: If he killed the poor woman, he deserves to die. It's as simple as that - an eye for an eye, tooth for a tooth.
