Every ‘shocking’ event and many a sudden turn of event, these can be due to the agencies of only one or a tiny handful of people. This reality infuriates many people who think there always has to be some sort of grand conspiracy and multiple actors. Always suspicious of the possibility of multiple actors, mobs have gone on the rampage after assassinations, etc. to seek out people to punish. We call these ‘witch hunts’. The absolute need to see conspiracy where there is something simpler is easy to psychologically understand for most people think they are helpless except when acting as a mob. The carnage caused by this belief and emotional reaction is immense, such as WWI, for example, or the Nazis to give another hideous example.
