Kesava Kasmiri's Commentary
By abandoning this war for righteousness not only would Arjuna lose his excellent reputation but great misfortune would arise as well. This is the gist of using the word akirtim meaning infamy. Instead of being the valiant warrior, Arjuna the weilder of the intrepid Gandiva bow has become timid and fled the battlefield. Such undying infamy would spread by word of mouth throughout the world in many countries by those who witnessed it. But not only ksatriya warriors would speak ill of Arjuna but also demi-gods, sages, merchants and even low class sudras. It might be put forth that isn't infamy better than death? And that one should bear it instead of dying. In the Mahabharata it is stated that one should try to defeat the enemy by: negotiation, bribery, open attack, etc. but should not fight if success is not guaranteed. In that case war should be avoided. To this Lord Krishna is responding that this infamy is more painful than death? Arjuna has never been defeated in battle, he is the son of the king of the demi-gods Indra, he is the dear friend of Lord Krishna, he possess unrivaled valor, possessing extremely praiseworthy virtues with this understanding infamy is much more painful than death.
