I'm going to be a bit of socialist about this and say that I don't necessarily think that we're all selfish and wicked people, but that due to the nature of the society in which we live, we are somewhat corrupted by it and act in bad ways. Ultimately, I think most people are good people at heart, though certain situations and events push people to act selfish and wicked. Obviously not everyone is a good person, but I think everyone has the potential to be one.
