In desperation, Duryodhan asked Karna to stop Ghatotkach. Karna had to use the divine weapon given by Indra and killed Ghatotkach. Seeing this, Bheem said angrily, “Krishna, my son is dead and you are laughing.” Lord Krishna said, “From the day this war started, I have been keeping Arjun away from Karna. I am laughing because Arjun is safe now.” Thus, Karna made himself vulnerable against Arjun. When Karna soon stood face to face with Arjun, his charioteer was suddenly killed and one of the wheels of the chariot broke down. Karna requested, “Arjun, stop fighting while my wheel is fixed. I am unarmed and it is unethical to attack me.” However, Lord Krishna said, “Karna, this war is unethical in itself. It will be foolish of Arjun not to take this opportunity to kill you.” Thus, Arjun killed Karna and the Kaurava army began to flee away from the battlefield. After Karna’s death, Duryodhan went missing and the Kaurava army surrendered.
