Therefore we are not worthy to kill the sons of Dhṛtarāṣṭra, our own kinsmen. For how, by killing our own, could we be happy, oh Mādhava?

The reasoning culminates: tasmāt (therefore, from this) — the logical conclusion of the previous analysis. Na arhāḥ (not worthy, not deserving) — moral unworthiness precedes any pragmatic calculation. Crime precedes punishment; the loss of arhatva (worthiness) is the first damage.

Sva-bāndhavān (our own kinsmen) and sva-janam (our own people) repeat sva (own) as a mantra of belonging. The hi (for, certainly) introduces the rhetorical question katham (how?) — the logical impossibility of happiness (sukhinaḥ) after parricide.

Mādhava (descendant of Madhu) is Kṛṣṇa as a member of the Yadu dynasty, reminding Arjuna of the family ties that transcend the war division.
