I have always been interested in things like this. What drives a person to do what they do......I do not believe that it is morbid or sick at all. If it weren't for people like us, then there would be no profilers or forensic psychologists
I see this as no worse than someone wanting to know how an engine works......what makes it run.......it's along the same line of thinking. Just like anyone interested in intricate clock works and such. Different strokes for different folks
