Implementation of the legitimacy of self-retaliation in Iran's criminal system and Islam with social expediency

In this paper, using the library method, we analyzed and analyzed the issue of "the implementation of legal retributivities in the penal system of Iran and Islam with social expediency" and explained the position of "retribution" in the criminal system of Islam and Iran and its adaptation to social expediency And in the opposite direction, it is necessary to presume that preserving the punishment of "retaliation" for social expediency, the deterioration of society from the crime of self and members and interests, as well as the preservation of the dignity of the physical integrity of the people of society. Crimes against physical integrity include violent crime. These crimes are committed against the body and the soul, in contrast to what (contrary to the property) are the only human property and part of his existence. Hence, in my opinion, in various legal systems, punitive penalties are imposed on perpetrators of such crimes. This hardship in the law of Hammurabi, as the oldest human-law law of four thousand years, is in the Sharia of Moses (as) and other religions, in the laws of the old civilizations (such as Iran and ancient Rome), as well as in Today's laws are observed in countries.
