I wish I had something eloquent to say here. But what I've realized that the online world is not any lesser or greater than the real one, it's just a completely different one with it's own social dynamics. People impart virual actions on each other with real consequences.
Otherwise I don't think I have special insight into people's morals and ethics. People remain complicated. You just get a better chance to see them in a different light when you expose them to a different medium.
Can't wait to see how people will behave in VR worlds, if it were to take off ;)
