@whiteplane - That's true, I can't argue that there is a dark side to human nature. But look at all the positive stories that come out of trying situations. You hear touching stories of sharing, self sacrifice, brotherhood, familial love and on and on. People are capable of great evil but also great love. I really believe this.
It's easy to get weighed down by the negative. The world can be a deeply sad and disappointing place. But if you are going to wake up every day and go out and be a part of this world then you have to believe that that is worth something and that this place is worth living in. You have to believe that there is more goodness than badness or what is the point?
