The case of Dr.Marcel Petiot. This guy is on cold and cruel bastard. He sold himself as an organizer of an escape route from Nazi occupied Paris during WWII but instead once his victims were lured he robbed them and murdered them.I have a facination as to why he of course WOULD do this as he was very well off and as a bonus he was not even a Nazi agent or sympathizer. Its just so chilling that nobody knows how many of those who were persecuted by the Nazis could have lived if it werent for this nut.
