I want to include one in this list. It's Silas from the Da vinci Code. This religious fanatic dumbass had such a heavy problem with self flagelation, that the dick strapped a spikey chain to his tight, bleeding him out and thus weakening him... that, just as he had to accomplish a delicate and complex hit on the main charachters. So, he was easily reduced. He didn't had the same coldness and professionalism that other religious fanatics usually have.
