A fascination with dead bodies..normal?

i'm completely fascinated with dead bodies, the human decaying process, and, well, death in general. it just really fascinates me. i read the book "stiff" by mary roach and absolutely loved it. i find myself looking at dead people on the internet, trying to figure out what stage they are at in the decaying process, what happened to them, how they were killed, etc. i also read "the psychopathology of a serial murder" by stephan j. gianngelo, and loved that as well. is something wrong with me? it's not normal to like dead bodies, even to the point of looking at them on the internet, right? do i have a risk of becoming a killer? what should i do to stop this awful fascination?
