I do not enjoy horrible things. However, I do appreciate the funeral somberness that such can bring. I've always had a morbid/depressive bent to me, and that comes through in the kind of literature, movies, and music I like. With that said, I do not feel it helps people to pointlessly shock people's systems, like gore movies do. But presented in a way that respects the dead, you could certainly tell the stories of those who had suffered, and that can lead people to greater empathy. I think often that people run away screaming from anything morbid, heavy, or painful, and so never learn how to deal with pain, or relate to the hurting.
