drptam ksatram bhuvo bharam
phalguny api krte ’mhasi
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
When the royal dynasty, being excessively proud because of the material modes of passion and ignorance, became irreligious and ceased to care for the laws enacted by the brahmanas, Parasurama killed them. Although their offense was not very severe, he killed them to lessen the burden of the world.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The ksatriyas, or the ruling class, must govern the world in accordance with the rules and regulations enacted by great brahmanas and saintly persons. As soon as the ruling class becomes irresponsible in regard to the religious principles, it becomes a burden on the earth. As stated here, rajas-tamo-vrtam, bharam abrahmanyam: when the ruling class is influenced by the lower modes of nature, namely ignorance and passion, it becomes a burden to the world and must then be annihilated by superior power. We actually see from modern history that monarchies have been abolished by various revolutions, but unfortunately the monarchies have been abolished to establish the supremacy of third-class and fourth-class men. Although monarchies overpowered by the modes of passion and ignorance have been abolished in the world, the inhabitants of the world are still unhappy, for although the qualities of the former monarchs were degraded by taints of ignorance, these monarchs have been replaced by men of the mercantile and worker classes whose qualities are even more degraded. When the government is actually guided by brahmanas, or God conscious men, then there can be real happiness for the people. Therefore in previous times, when the ruling class was degraded to the modes of passion and ignorance, the brahmanas, headed by such a ksatriya-spirited brahmana as Parasurama, killed them twenty-one consecutive times.
In Kali-yuga, as stated in Srimad-Bhagavatam (12.2.13), dasyu-prayesu rajasu: the ruling class (rajanya) will be no better than plunderers (dasyus) because the third-class and fourth-class men will monopolize the affairs of the government. Ignoring the religious principles and brahminical rules and regulations, they will certainly try to plunder the riches of the citizens without consideration. As stated elsewhere in Srimad-Bhagavatam (12.1.40):
prajas te bhaksayisyanti
Being unpurified, neglecting to discharge human duties properly, and being influenced by the modes of passion (rajas) and ignorance (tamas), unclean people (mlecchas), posing as members of the government (rajanya-rupinah), will swallow the citizens (prajas te bhaksayisyanti). And in still another place, Srimad-Bhagavatam (12.2.7-8) says:
evam prajabhir dustabhir
yo bali bhavita nrpah
praja hi lubdhai rajanyair
Human society is naturally grouped into four divisions, as stated in Bhagavad-gita (catur-varnyam maya srstam guna-karma-vibhagasah). But if this system is neglected and the qualities and divisions of society are not considered, the result will be brahma-vit-ksatra-sudranam yo bali bhavita nrpah: the so-called caste system of brahmana, ksatriya, vaisya and sudra will be meaningless. As a result, whoever somehow or other becomes powerful will be the king or president, and thus the prajas, or citizens, will be so harassed that they will give up hearth and home and will go to the forest (yasyanti giri-kananam) to escape harassment by government officials who have no mercy and are addicted to the ways of plunderers. Therefore the prajas, or the people in general, must take to the Krsna consciousness movement, the Hare Krsna movement, which is the sound incarnation of the Supreme Personality of Godhead. Kali-kale nama-rupe krsna-avatara: Krsna, the Supreme Personality of Godhead, has now appeared as an incarnation by His holy name. Therefore, when the prajas become Krsna conscious, they can then expect a good government and good society, a perfect life, and liberation from the bondage of material existence.
