Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Any cruel person — be he a man, woman or impotent eunuch — who is only interested in his personal maintenance and has no compassion for other living entities may be killed by the king. Such killing can never be considered actual killing.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The planet earth is actually a woman in her constitutional form, and as such she needs to be protected by the king. Prthu Maharaja argues, however, that if a citizen within the state — be he man, woman or eunuch — is not compassionate upon his fellow men, he or she may be killed by the king, and such killing is never to be considered actual killing. As far as the field of spiritual activities is concerned, when a devotee is self-satisfied and does not preach the glories of Krsna, he is not considered a first-class devotee. A devotee who tries to preach, who has compassion upon innocent persons who have no knowledge of Krsna, is a superior devotee. In his prayer to the Lord, Prahlada Maharaja said that he was not personally interested in liberation from this material world; rather, he did not wish to be liberated from this material condition until all fallen souls were delivered. Even in the material field, if a person is not interested in others’ welfare, he should be considered to be condemned by the Personality of Godhead or His incarnation like Prthu Maharaja.
