Every once in a while people behaved in good ways, however, for the most part, people are terrible. People will just do whatever they have to do in order to get what they want. In truth, they don't care about anyone. People are greedy, and if other people suffer for their own gain they don't care.
Yes, some people will steal anything from anybody. They are people who either get a high from the act of stealing, or possibly just desperate people who think they need everything. They may even feel like others don't deserve to have certain things. However, as easy as it would be to just say society's going down the tubes, we need to remember that the vast majority of people do not steal and are actually good honest caring people.
People aren't inherently bad or greedy, so I don't think it is fair to assume that they would be willing to steal anything from anyone. Of course there are bad eggs and those with kleptomania, but I think the average Joe does have a conscience and knows what is inherently wrong.
No, most people will not steal anything from anybody but some bad people will. Most people are too scared of going to prison to steal from other people. Furthermore, most people do not want people to believe that they are a bad person. This keeps people from stealing from others.
