Krishna tests Karna (stoicism two)

After Kunti meets Karna and returns with an assurance from him that he would not kill any Pandava except Arjuna and that he would not reuse any arrow during his war against Arjuna, Lord Krishna meets Karna. Sri Krishna tells Karna very clearly that Pandavas would win the war and become the emperors. Krishna asks Karna to join Pandavas so that he (Karna) could become the next emperor. Krishna tells Karna that irrespective of whether he joins Pandavas or not, Pandavas would emerge victorious. But, Karna flatly tells Krishna that he would not shift loyalty. Why Krishna tried to entice Karna at such a critical stage of the war was to show Karna’s stoicism to the world. Krishna wanted the world to know the character of Karna.
