Online there are very few consequences to actions it seems, so people are in the frame that what they do is okay. In real life there are other factors besides laws that temper actions and when one lives in a community, reputation and behavior matter to some degree. Not many people openly steal from their local store or set fire to their neighbours home - the only thing really stopping anyone doing anything are the consequences of actions that people fear, as well as their own character. Not everyone would steal or set fire to things regardless of whether they could or not.
