Morbid and beautiful

Last night when I couldn't sleep because of some really bad nightmares, my mind started contemplating on a question I've been asking myself for some time: why do many people feel attracted to the morbid, the dark and death?
What is it that fascinates us about terrible urban legends, stories of murder,death and despair?
Oh, there are many questions here, and I don't know how to answer all of them.

First of all: Every person on this planet has both darkness and light in their hearts. This isn't meant like a religious observation, but we have the seeds to do both good and bad. We can choose (free will isn't it?) to be nice to someone, or not.
So here lies part of the answer I'm seeking. The darkness we encounter will in some cases be found extremely fascinating, while in other will we try to escape it, and go back into the light. There is nothing right or wrong in seeking the darkness and the gloomy paths of life. We choose and live with our choices. And we cannot see one thing without the other. It is a shame that today people see death as entertainment, but after all has death been somewhat fascinating for humankind since the first day. Nothing has returned from "the other side", and the whole thing is surrounded by mystical ideas and sometimes superstition.

Once again has this post run astray...
What I was trying to say is that these dark interest awakens something in us that has been kept captive all our lives, that wants to break free...
Our society still worships the sun and the light, so anyone who has seen that there's an other way to knowledge will experience condemnation from the society he or she is a part of.
The moon has more followers than people like to think, and when it's full will they howl against it, pour all their hate and sorrow out for all to see, even the mortal sun-worshippers.
