Emil Blonsky vs Richard Speck
Two villains, one criminological theory: XYY chromosome. We compare Emil Blonsky and Richard Speck: their profile, how dangerous they are, and where they meet and part.


Emil Blonsky and Richard Speck share neither a film nor a universe, but they share something deeper: the same criminological theory explains them, XYY chromosome. 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 manipulation: Richard Speck beats Emil Blonsky by 13 points.

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.
