Soviet serial killer Andrei Chikatilo just may be the sickest serial killer I've ever read about. I wrote a paper on him in my Homicide Investigation class and actually had nightmares. It wasn't an easy paper to write, let me tell ya.
Like I said before, I have yet to read about anyone sicker than Albert Fish. Various serial killer have been known for one grizzly aspect or another but Fish's activities seemed to stretch across the entire spectrum. It's possible he had upwards of 100 victims - mostly children - kidnapping, raping, torturing, killing, and eating them.
