Am I mentally ill? Does this mean I'll be a killer?

I'm a sixteen-year-old girl who grew up watching movies like "Texas Chainsaw Massacre" and "Psycho." I've always had a fascination for twisted, demented things. When I go online, I don't look up normal girl things such as clothing and quizzes...I look up serial killers and read about them for hours. I'm not repulsed like all my friends when there is a gruesome scene in a movie; I love it! Now, I'm not as weird as I sound, I promise. I have tons of friends, a great family and am deeply in love with my boyfriend of three years. But when I hear about someone getting shot, I literally am bored with the story. I want to hear about cannabals and sadistic killers who feel no remorse: Ed Gein and Albert Fish! Ted Bundy and Jeffrey Dahhmer! It's not like I idolize these people, but I'm strangely interested in every thing there is to know about them. What the hellll? Does it have anything to do with my chronic depression or eating disorder? Or my past suicide attempts? I'm perfectly happy now, I just don't understand it!
