A good ruler must prod his people gently in the direction of dharma, which lies in the centre, in balance. If there is too much anger in society, leading to chaos and disruptive violence, then the leader needs to move it towards stability and calm. If, on the other hand, a society is passive and uncomplaining, then the leader needs to incite active participation and outrage, even anger, among the people.
Mahabharata
Pandavas - passive
Draupadi - anger
Krishna - leader
