 The deeper explanation for the prevalence of torture cultures and the difficulty of eradicating institutionalised torture is no doubt very complex, but presumably it consists in part in the following elements: (1) moral docility, as opposed to physical docility, is a feature of individuals housed in, and materially dependent upon, large, hierarchical, bureaucratic organisations with strong, relatively homogenous cultures; (2) the roles of soldier, police officer, and prison warder necessarily involve the routine use of coercive, and even deadly, force against dangerous criminals, enemy soldiers, or terrorists, and therefore undertaking these roles inevitably results in a degree of moral de-sensitisation and a sense of moral ambiguity when it comes to torturing criminals and/or terrorists; (3) torture is an exercise of enormous power, and power is deeply seductive to many people (and much less dangerous than shooting at armed enemy combatants or trying to arrest or subdue violent criminals).
