Final answer:
Emile Durkheim's Functionalist perspective views normal levels of deviance as necessary for society due to its contribution to overall stability.
Step-by-step explanation:
The sociological theory proposed by Emile Durkheim that views normal levels of deviance as necessary for society since it contributes to its overall stability is the Functionalist perspective. According to Durkheim, deviance serves a purpose in society by reinforcing social norms and reminding people of the consequences of violating them.
For example, when deviant behavior is punished, it reaffirms the existing cultural values and norms. Deviance can also challenge societal views and lead to social change, as seen in movements like the civil rights sit-ins.
