Anyone who *orders* torture must have some degree of psychopathic personality disorder, at the least, especially in the knowledge that torture produces garbage "intelligence". Torture is fundamentally against any principles of civilized human conduct. Those who *execute* methods of torture would, of course, benefit from having a psychopathic kind of personality, but the consequences of disobeying orders is likely to be considered more important than any moral issues raised by torturing people; in the military, shit rolls downhill, (aka chain of command).
There are people in very senior positions in this administration who exhibit psychopathic traits. Furthermore, when many of the neoconservatives within (and associated with) the Bush Administration have a blatant track record of hatred and phobia towards arabs and muslims, and that a principle aim of the neoconservatives within this administration is to demonize the muslim community worldwide..... it's hardly surprising that torture would be part of their M.O. They probably even derive pleasure from the knowledge that they have the power and motivation to inflict great pain from the comfort of their offices and executive suites.
