• anāgasām — of the sinless ones
  Genitive plural of anāgas — without offense. The technical Bhāgavata word for the innocent victims (Devakī's children, the cowherds, the cows). Kaṁsa's violence is named anāgasām droha — violence against the offenseless. Asuric karma's heaviest signature.
• droham — violence, malice
  From √druh (to be hostile, to wish-harm). Specifically malicious harm, not battlefield violence. The Bhāgavatam distinguishes — Cāṇūra's combat is yuddha; Kaṁsa's life-pattern is droha. Only droha disqualifies one from śam.
• bhūta - dhruk — one hostile to creatures
  Compound: bhūta (creature) + dhruk (from √druh). The technical name for the harming-personality. Cf. BG 18.45-46 — bhakti is sva-karma defined as ahiṁsā; bhūta-dhruk is its antonym. The widows speak Gītā-grammar without knowing it.
• śam — peace, happiness
  From √śam (to be quiet, at peace). The Vedic name for the fundamental wellbeing. The widows ask, kaḥ labheta śam — who could attain it? The answer the Bhāgavatam will give in chapter 73 (the Pāṇḍava-rāja-sūya) is: those who take shelter of Kṛṣṇa. Śam follows śaraṇa.

'You committed great violence against innocent beings; how can one who harms others ever attain happiness?' Even the widows, mid-lament, accidentally speak the verdict on Kaṁsa's life. Their grief becomes the chapter's epitaph for adharma — written by the very people whose love it cost.
