In the Kurukshetra War, Karna is Duryodhana's greatest champion and serves as commander from the fifteenth day. Duryodhana sincerely believes that Karna is superior to Arjuna, and will defeat his four brothers. When Karna is killed, Duryodhana mourns his death intensely, even more so than the death of his own brothers and was inconsolable. When Karna's identity is revealed to him, Duryodhana's love for Karna only grows and it is said to be he, and not the Pandavas, who performs Karna's last rites. Krishna confirms that he has the highest right over Karna, as they loved and supported each other truly.
