They are paid for fighting

Madhudviṣa: We brought back Wally one picture from India on the battle of Kurukṣetra of Abhimanyu. Abhimanyu's head was there, and Karṇa was on the ground with his chariot, and Arjuna was about to kill him, and Kṛṣṇa was directing him to kill. So I told Wally the story that when Abhimanyu was surrounded by the mahārathīs, there was no mercy then, so now Karṇa was objecting that...

Prabhupāda: Injustice.

Madhudviṣa: ...he cannot shoot a man if he gets off his chariot. And Kṛṣṇa said, "There was no mercy with Abhimanyu, so therefore there will be no mercy now."

Prabhupāda: Tit for tat. (laughter)

Guest 1: But where was the generosity then?

Prabhupāda: That is happening, tit for tat.

Guest 1: Was that generosity, or...? Where was the generosity?

Prabhupāda: No. That is war tactics. That is war tactics. Sometimes we have to use war tactics because we have to own victory. But they were generous because in the Battlefield of Kurukṣetra they would fight like anything, like enemies, but at night they were friends. The one man is going. Just like sportsman. They fight during the play, but after that, they are friends, talking together, drinking together, like that.

Guest 2: Like barristers and prosecutors.

Prabhupāda: (laughs) Yes. They are paid for fighting. (laughter) But when the fighting is over, they are friends.
