Le Chiffre vs Professor Moriarty
Two villains, one criminological theory: Intelligence (IQ) and crime. We compare Le Chiffre and Professor Moriarty: their profile, how dangerous they are, and where they meet and part.


Le Chiffre and Professor Moriarty share neither a film nor a universe, but they share something deeper: the same criminological theory explains them, Intelligence (IQ) and crime. That makes their face-off more than a “who would win?”: it is the same mechanism of crime taking two different shapes. The biggest gap is in violence: Le Chiffre beats Professor Moriarty by 25 points.
The face-off · criminal profile
On paper, the more dangerous one is Le Chiffre, with a danger index of 76/100 against 72. But paper isn’t everything.
The index weighs violence, manipulation and intelligence, and subtracts empathy (the colder, the more dangerous). It is a reading for debate, not a sentence: the theory matters more than the score.
