The war in former Yugoslavia is characterized by extreme cruelty condi
tioned by the some initial psychosocial factors: 1) Crisis and frustra
tion which produced transferred aggression; 2) National character whic
h has been formed in history; 3) Communist indoctrination which result
ed in obedience and an obsession with the enemy; 4) Stigmatization of
ethnic groups based on old historical feelings of resentment. Most sla
ughterers are not psychopaths or other insane people, but ordinary cit
izens. In the Balkans the authoritarian relations, the feeling of depe
ndency, and an extreme compliance to tradition, myths and authorities
are widespread. Some authors refer to about inborn and genetically det
ermined aggression which becomes inhibited by internal controlling str
uctures (called the Supergo, stages of morality, internal standards or
moral values). Severe crises like war show that these structures are
not totally autonomous. They cannot function properly without some fee
dback from the environment; otherwise they quit and are replaced by id
eology.
