The "Duper's Delight" burst of dopamine in Martin Shkreli's vacant frontal cortex makes all the difference eh? The sense of 'something off kilter' with them. Which is why many of them have no choice but to start/enter cults as they were too creepy for society and basically have to hide away.
As I was saying about psychopaths and chess. It is the one game they are often good at, as it requires deviousness and deception in order to win and it is not a creative game - just one based on previous predatory memories.
