Jeeves' Diary

It seems, sociopathy is not always caused by aggression. But much of aggression consequently goes out of sociopathy. No matter that arguments to justfy such a behavior can be far-fetched. Far more important that roots of it are very deep, sometimes going into childhood. Something was marked like “unpleasant sign” in someone's memory, then it accompanied his or her psychical trauma over the time of life . These signs are just “hyperlinks” leading to “site of our unconsciousness” that shows what and how it was. Actually it was really bad, unpleasant or painful by then… Many years after, it is enough to see a tiny sign of this kind to him or her, to get instantly furious and insane. Reaction of such sociopath may be triggered by any thing – smell, color of you jacket, too loud or pitched laughter, etc.
