In general, mankind is evil. The only thing that keeps people doing, what we like to call wrong or right, is fear of consequences. Anonymity has taken this away. What you see in online forums of all kinds (games, forums, blogs, etc..), is the true nature of mankind. I can be what I want to be, and no one can do anything about it. People who act kind in game, do so because they choose to. People that don't, do so because they choose to. There is no magical misconception that the other people you interact with day by day in online forums isn't a real person.
