Reminiscent of 'Blindsight', an SF novel by Peter Watts. Humans have resurrected the genes of vampires (don't stop reading! it's hard SF) who are psychopaths and humans' predators, with concomitant higher intelligence. For this intelligence and dispassion they're the perfect choice to command in life and death missions. It's a good book, and it contains a lot of the feel of this guy.
