Natural disasters like, earthquakes, floods, hurricanes, volcano blasts and Tsunamis cause great damage or loss of life in certain portions of the land or a few people of particular area.
Scarcely do we see some disasters occur owing to the dictatorship of a few rulers. And all the people of a nation or the earth suffer with these dictators. Our mythologies say demon Narakasura was one of the most sadistic rulers, who brought all kingdoms on the earth together and ruled it. Furthermore, he eyed on ruling Swargaloka (heaven). Finally the demon was killed by lord Sri Krishna and Satyabhama in a face to face battle.
In Kaliyuga too, we come across the rulers like Narakasura who make all people of their countries suffered. Adolf Hitler stood as one best example of all times, who not only made all the people of his country suffered but also held responsible for the second world war which,further, led the deaths of lakhs of soldiers in battle fields. In the contemporary world too, every now and then, we hear the names of some of the rulers who develop the attitude like Hitler in world countries and make all the people of their nations suffered.
