I wonder, what is the use of Shatrughna in the Ramayana, He hardly has anything to do. Similarly in the Mahabharat, the youngest two of the Pandavas, Nakul and Sahadev, they don’t bring much to the epics. As for the hundred Kauravas, only Duryodhana and Dushasana have a role to play. The rest of the ninety eight are just born and get killed in the war. For the rest of the story, they add body mass.
What was the use of adding these characters, and then telling us nothing about them?
