Bhagavad-gita As It Is Lectures

We were talking of not killing, that why should you kill one animal who is coming to attack? No. You must kill. That is necessity. You should not go to the forest to find out some living entities, living beings, to kill. That is not your business. That is hiṁsa. But if a tiger comes to attack you, you must kill. That is self-defense. And that is not hiṁsa.

Lecture on BG 2.2 -- London, August 3, 1973:

People are very much, nowadays, eager how to stop war. But Kṛṣṇa says... (break) ... at any case is not required. There is necessity of war. Just like He's trying to convince Arjuna. Our war means... According to Vedic civilization, that is dharma-yuddha, religious fight. When the actual need is there to fight, we must fight. Not that when there is need of fight, one becomes nonviolent. Just like yesterday in the evening, when we were talking with Dr. Shoemaker, so they were supporting that "Why should you kill any animal who is coming to... If you are determined not to kill..." We were talking of not killing, that why should you kill one animal who is coming to attack? No. You must kill. That is necessity. You should not go to the forest to find out some living entities, living beings, to kill. That is not your business. That is hiṁsa. But if a tiger comes to attack you, you must kill. That is self-defense. And that is not hiṁsa. So a devotee knows, a Kṛṣṇa conscious person knows when to kill and when not to kill. But it is not that because we accept not killing, therefore in every case, killing should be stopped. No. If there is necessity, killing should be accepted. Therefore Arjuna decided not to kill, not to fight. And Kṛṣṇa says that "This is anārya-juṣṭam. this kind of decision is made by the uncivilized rascal." Anārya-juṣṭam asvargyam akīrti-karam (BG 2.2). So many things, He says. Asvargyam. Because the aim of human life should be to make progress. That is called ārya, progressive march.
