Deviance used correctly

I believe that deviance can be a good thing, only if used correctly. Deviance can lead to change and reform which can be good, but not always. If a person is acting deviant to promote a good cause then, yes, that is deviance being used correctly. But in most cases deviance is not a good, or healthy, thing. People should not act outside of the social norms or be deviant on purpose. For example, coming to school naked would be breaking the social norms and unsaid understanding that you just don't do that. Therefore, this is a deviant, and illegal, act.
