re: Your most loathsome character in movie/tv show?

It's hard to argue with this guy being the most loathsome:

Amon Göth

"Göth personally murdered prisoners on a daily basis. His two dogs, Rolf and Ralf, were trained to tear inmates to death. He shot people from the window of his office if they appeared to be moving too slowly or resting in the yard. He shot to death a Jewish cook because the soup was too hot."

I loved the way he was hanged at the end. The Russian officer just kicks the legs of the stool until they break, then he just dangles and strangles.
