Oh , I agree with you . I was exceptionally deliberate in my choice not to use the terms insane , sick , diseased or terms that would imply impairment or lack of control . It ' s a difficult category to pin down , but a lot of people put those engaged in behavior radically divergent from their accepted norms in a category that they call crazy or some such , but might be better phrased dangerously unrelatable other . It ' s a failure of terminology . What do you call someone who ' s behavior is so radically antisocial that you can ' t perceive a rational line of reasoning that gets someone to where they are ? The unibomber is not medically afflicted . I can understand his philosophy and it ' s consequences , although I disagree . I can ' t grasp the jump from there , to leaving bombs in alleys .
