Is it a bad thing to be morbidly curious?

It's not that I enjoy these things, it's more out of curiousity. The thing is, I can't stop watching these gory videos. I would see videos of beheadings, suicides, murders and gruesome pictures of people self mutilating but to the extreme and it disgusted me but I watched more. I don't understand if what's going on is a bad or good thing. What do you think about this?
