1.43 Sri Sankaracharya did not comment on this sloka. The commentary starts from 2.10.
1.35 1.44 Nihatya etc. upto anususruma. Sin alone is the agent in the act of slaying these desperadoes. Therefore here the idea is this : These ememies of ours have been slain, i.e., have been take possession of, by sin. Sin would come to us also after slaying them. Sin in this context is the disregard, on account of greed etc., to the injurious conseences like the ruination of the family and the like. That is why Arjuna makes a specific mention of the [ruin of the] family etc., and of its duties in the passage How by slaying my own kinsmen etc. The act of slaying, undertaken with an individualizing idea about its result, and with a particularizing idea about the person to be slain, is a great sin. To say this very thing precisely and to indicate the intensity of his own agony, Arjuna says only to himself [see next sloka]:
1.26 - 1.47 Arjuna said - Sanjaya said Sanjaya continued: The high-minded Arjuna, extremely kind, deeply friendly, and supremely righteous, having brothers like himself, though repeatedly deceived by the treacherous attempts of your people like burning in the lac-house etc., and therefore fit to be killed by him with the help of the Supreme Person, nevertheless said, I will not fight. He felt weak, overcome as he was by his love and extreme compassion for his relatives. He was also filled with fear, not knowing what was righteous and what unrighteous. His mind was tortured by grief, because of the thought of future separation from his relations. So he threw away his bow and arrow and sat on the chariot as if to fast to death.
By the faults of mixture of castes, both the caste rules and the family rules will be destroyed (utsadyate).
Persons whose family traditions have been destroyed means also those whose caste and heritage has also been lost. We have heard from the authoritative sources of the Vedas scriptures that those addicted to vice who perform no expiation nor feel any repentance, go to terrible hells full of misery.
Madhvacarya has no commentary so we present Baladeva Vidyabhusanas. Here by the word kula-dharma getting spoiled also means that jati-dharmah meaning the duties of each caste and asrama dharma meaning the relationships between the castes are indicated as well. Anususruma means we have heard in the line of parampara disciplic succession that persons who are addicted to sinful activities; yet who do not make atonement or repent are damned to excruciatingly painful and terrifying hells.
There is no commentary for this verse.
Arjuna is supporting his argument by affirming that he has heard from respectable sources in disciplic succession, that those who are responsible for destroying righteousness reside permanently in hellish existence. Therefore this decision to fight is not the wisest of choices.
