SB Canto 10.1 to 10.13
In a peaceful attitude, Vasudeva began to address Kaṁsa by putting forward reasonable arguments.
SB 10.1.36, Purport: Vasudeva, who was to be the father of Kṛṣṇa, is described here as mahā-bhāga, a very upright and sober personality, because although Kaṁsa was ready to kill Vasudeva's wife, Vasudeva remained sober and unagitated. In a peaceful attitude, Vasudeva began to address Kaṁsa by putting forward reasonable arguments. Vasudeva was a great personality because he knew how to pacify a cruel person and how to forgive even the bitterest enemy. One who is fortunate is never caught, even by tigers or snakes.

Krsna, The Supreme Personality of Godhead
Lord Brahmā and Lord Śiva lost their peaceful attitude upon a slight provocation.
Krsna Book 89: After hearing of Bhṛgu Muni’s experience in meeting all three predominating deities—Lord Śiva, Lord Brahmā and Lord Viṣṇu—the sages concluded that Lord Viṣṇu is the Supreme Truth, the Personality of Godhead. It is said in Śrīmad-Bhāgavatam that after hearing the details from Bhṛgu Muni the sages were astonished because although Lord Brahmā and Lord Śiva were immediately agitated, Lord Viṣṇu, in spite of being kicked by Bhṛgu Muni, was not agitated in the least. The example is given that small lamps may be agitated by a slight breeze, but the greatest lamp or the greatest illuminating source, the sun, is never moved, even by the greatest hurricane. One’s greatness has to be estimated by one’s ability to tolerate provoking situations. The sages gathered on the bank of the river Sarasvatī concluded that one who wants actual peace and freedom from all fear should take shelter of the lotus feet of Viṣṇu. Since Lord Brahmā and Lord Śiva lost their peaceful attitude upon a slight provocation, how can they maintain the peace and tranquillity of their devotees? As for Lord Viṣṇu, however, it is stated in the Bhagavad-gītā that anyone who accepts Lord Viṣṇu or Kṛṣṇa as the supreme friend attains the highest perfection of peaceful life.
So there must be anger, not that God should be always peaceful. But the difference is His anger and His peaceful attitude produces the same result.
Lecture on SB 7.9.3 -- Mayapur, February 17, 1977: So everything is there. Don't think that God is zero. No. Śūnyavādi. Everything. Janmādy asya yataḥ [SB 1.1.1]. Athāto brahma jijñāsā. You are inquiring about Brahman. Paraṁ brahma paraṁ dhāma pavitraṁ paramaṁ bhavān [Bg. 10.12]. So there must be anger, not that God should be always peaceful. But the difference is His anger and His peaceful attitude produces the same result. Prahlāda Mahārāja, a devotee, He is very satisfied with Prahlāda Mahārāja and He is very much dissatisfied with his father, but result is the same: both of them got liberation. Although a devotee becomes associate whereas the demon who is killed by God, he does not become an associate... He is not qualified. But he enters into the spiritual kingdom. He gets liberation from this material bondage. So why a devotee should take the same position? Therefore, māṁ eti. Tato māṁ tattvato jñātvā viśate tad-anantaram. They viśate, enters, enters in the spiritual kingdom. Everyone who is liberated, he is entered.
