MahÄrÄja Yudhiá¹£á¹hira thought that although he was not actually involved in the administration of the kingdom, which was being carried on well by Duryodhana without harm to the citizens, he caused the killing of so many living beings only for his personal gain of the kingdom from the hands of Duryodhana. The killing was committed not in the course of administration but for the sake of self-aggrandizement, and as such he thought himself responsible for all the sins.
