Why is the concept of a stigma so critical to the concept of deviance?

When someone is stigmatized, it means that they are outcast by society; thus, a stigma is a social disapproval toward someone. 

When someone is described as deviant, they are seen as being outside the norm. This deviance from the norm often incites stigmatization, portraying the link between the concept of a stigma and deviance.

One of the important characteristics of this Code is that it follows the ‘eye for an eye principle’ which shows its antiquity. This is based on the equality of justice principle and is contrary to many modern principles of justice, like equity and good conscience.
