Among large-scale tragedies involving human suffering and the many examples of man’s inhumanity toward man, only a few capture our imaginations and sway our collective emotions. The question of which specific episodes achieve this special salience does not seem to depend on the scale of the suffering or even on the degree of immorality involved.
The salience instead arises through accidents and vagaries of history. The villains in particular episodes may have been primed to play such a role because of previous affinities and alignments and how we had already come to see them as villains. Some episodes get more Western press coverage than many other episodes because of where reporters happen to be, what competition there is for headlines, or other random influences. All of this makes for much inconsistency in what grabs our heartstrings as well as our attention.
