Yes. One thing that concerns me about the CIA is the question of motivation: How many are really seeking to do the right thing (within the limits of reality), and how many are chiefly looking out for their own interests or manias?
Of course, it's not strictly an either/or question, and I tend to believe that most of their employees are at least of average decency - but it is a question that all of us must ask ourselves on occasion.
That said, I am glad that the CIA has hardheaded agents who can see beyond the silly taboos our society has inflicted on itself, but I fear the intelligence services may attract individuals who are a bit too hardhearted as well - and naturally, hardheartedness could make the whole exercise of protecting national interests meaningless.
But a hardheaded agent will understand the difference between a threat and a warning, and the difference between aggression and self defense, where a self-serving politician or law enforcement officer will not - and understanding that difference can be a considerable contribution to protecting the national interests in itself.
Benjamin Franklin on the Rattlesnake:
"As if anxious to prevent all pretensions of quarreling with her, the weapons with which nature has furnished her, she conceals in the roof of her mouth, so that, to those who are unacquainted with her, she appears to be a most defenseless animal; and even when those weapons are shown and extended for her defense, they appear weak and contemptible; but their wounds however small, are decisive and fatal. Conscious of this, she never wounds 'till she has generously given notice, even to her enemy, and cautioned him against the danger of treading on her."
