Sociologists and psychologist sidentify external factors, which lead to violence. Economics and politics create depressed neighborhoods. Lack of parental care has left children without moral guidance. Violent images on television desensitize children. Scientific explanations are third person accounts.
Third person accounts analyze phenomena by enframing being and by viewing all being as things.
Things are shaped by physical forces. To say that I am violent because of society, or because of my parents, or because of television presupposes that the individual is not free, and does not make choices on their own. By saying that all is external, humans are reduced to a mere puppet pulled along by strings. They seeks to understand and explain general phenomena from the standpoint of individual lives, and of a given reality. Moreover, danger permeates what is alien and unknown.
