Devotee (3): I have seen kālī-pūjā.
Prabhupāda: Yes. But her business is to cut off the heads of the demons. She is carrying one head in this hand, and in this hand she's carrying a chopper, and her business is to cut the heads of the demons. But she's also the agent of the Supreme Personality of Godhead. How she's agent? Because God has got two business: paritrāṇāya sādhūnāṁ vināśāya ca duṣkṛtām (BG 4.8). Duṣkṛtino mūḍhāḥ, narādhamāḥ, māyayāpahṛta-jñānā āsuraṁ bhāvam āśritāḥ (BG 7.15). For them the goddess Kālī is engaged to cut their heads, kill them. That is also Kṛṣṇa's agent. Vināśāya ca duṣkṛtām, they have to be finished. But, by finishing them, they are also elevated. Finishing means finishing their sinful activities, finishing their sinful activ... Just like... It is very easy to understand. Just like a person who has committed murder, the state law is, "Finish him, otherwise he will commit another murder." If he's encouraged... Therefore, by finishing him, there are two purposes. One purpose is served that because he has done something very grievous sinful activity, by sacrificing his own life, he becomes relieved from the sinful reaction. That is the law in the Manu-saṁhitā. I have not manufactured. The murderer is condemned to death just to save him from many following resultant actions of sinful activities. If in this life, he gives his life, "Life for life," then he's safe. In the next life, he takes his birth clean, not suffering any more on account of the sinful activities. This is the statement in Manu-saṁhitā. Another instruction is that if this murderer is killed, then he will be saved from committing again murder.
So the vināśāya ca duṣkṛtām, when a demon is killed then he's saved, the people are saved, and everything is good. But people cannot understand that "Why God is killing the demons and giving protection to the devotees?" God is equal to everyone. Kṛṣṇa says, samo 'haṁ sarva-bhūteṣu na me dveṣyo 'sti na priyaḥ (BG 9.29). Kṛṣṇa says that "I am equal to everyone." If God is not equal to everyone, then how He can be God? He is God who is equal. Na me dveṣyo 'sti na priyaḥ. So when God is killing somebody, and God is patting something, somebody, that does not mean He has got two equal behavior for two persons. No. His behavior is the same: affection.
