As supreme teacher of the world, Lord Krsna condemns the attitude of Arjuna who said, "I do not find any good in this fighting. It will cause perpetual habitation in hell." Such statements by Arjuna were due to ignorance only. He wanted to become nonviolent in the discharge of his specific duty. For a ksatriya to be in the battlefield and to become nonviolent is the philosophy of fools. In the Parasara-smrti or religious codes made by Parasara, the great sage and father of Vyasadeva, it is stated:

ksatriyo hi praja raksan sastra-panih pradandayan

nirjitya parasainyadi ksitim dharmena palayet.

"The ksatriya's duty is to protect the citizens from all kinds of difficulties, and for that reason he has to apply violence in suitable cases for law and order. Therefore he has to conquer the soldiers of inimical kings, and thus, with religious principles, he should rule over the world."

Considering all aspects, Arjuna had no reason to refrain from fighting. If he should conquer his enemies, he would enjoy the kingdom; and if he should die in the battle, he would be elevated to the heavenly planets whose doors were wide open to him. Fighting would be for his benefit in either case.

Arjuna was a famous fighter, and he attained fame by fighting many great demigods, including even Lord Siva. After fighting and defeating Lord Siva in the dress of a hunter, Arjuna pleased the Lord and received as a reward a weapon called  pasupata-astra.  Everyone knew that he was a great warrior. Even Dronacarya gave him benediction and awarded him the special weapon by which he could kill even his teacher. So he was credited with so many military certificates from many authorities, including his adopted father Indra, the heavenly king. But if he abandoned the battle, he would not only neglect his specific duty as a  ksatriya,  but he would lose all his fame and good name and thus prepare his royal road to hell. In other words, he would go to hell, not by fighting, but by withdrawing from battle.
