Mankind is still evolving and learning. We have not learned that greed and jealousy, hatred and murder do not really win a war. We are young and liable to fall, a lot. But I think we are growing up and starting to take responsibility for some of our mistakes and trying not to make any more. But I truly believe, the meek who are supposed to inherit the earth, need to start speaking up and standing against the people who are wrong, so we can evolve faster. : D
Yes. Darkness is in the heart of man from his birth. Contrary to the world's view, we are not born innocent. Evil is not simply a learned behavior, though our upbringing often influences that innate evil, just observe any two year old and you will see their greed and jealousy will support that fact.
