Deviance

For the most part deviance is pretty unacceptable in society, but there are times when it can be a good thing.  For example, when everyone around you becomes mentally unstable due to brainwashing or any reason, it would be a good time to act defiantly towards them in order to set things straight.  It would be a bad thing if someone were to act defiantly for no reason just to cause chaos. Therefore, deviance is acceptable in extreme measures but usually shouldn't be brought out.
