As far as the brutalizing of the balkans peoples. Isn't it interesting that every group who has had anything to do with the balkans has brutalized them or had to rule them with an iron fist? Could it be that the fact that those people when not fighting with the latest ruler would just assume fight each other also? The most peacefull it was there was with Turkey and then Yugoslavia.
Something about their upbringing? Or maybe they just never wanted to join up civilization wise with the modern world and their neighbors because of their own problems of state management.
Maybe they need firm (not brutal) governance. Some peoples seem to be like that.
As far as your comment about Balkan peoples, your knowledge of history is dismal. And I just don't have the time...
