Prahlāda Mahārāja, he was very much tortured by his father because he was a devotee. That is the function of the non-devotees: to tease the devotees. That is not very new thing. That is old. Even the father. So when he was too much teased, then Lord appeared in Nṛsiṁha mūrti to kill the demon, and He was very much angry. You see? Even a neighbor's child, if he is tortured by his father, you will be angry, that "Why you are torturing this little child?" And what to speak of Kṛṣṇa? And especially His devotee, Prahlāda Mahārāja, was being tortured.
Kṛṣṇa appeared as Lord Buddha because people tortured these ordinary animals. Sadaya-hṛdaya-darśita-paśu-ghātam (Śrī Daśāvatāra Stotra 7).
We pray in that keśava dhṛta-buddha-śarīra. The meaning is that He appeared as Lord Buddha, being compassionate on the animals, who were being tortured by the human being. Of course, there is law to punish them, but sometimes the Lord becomes very much tortured Himself when His sons, or may be animals, they are tortured. Otherwise, how He is father of everyone? You see.
So the torturing business of the demons is going on. Going on. As soon as the demons finds somebody little weak, they will torture. Weak in their way. A devotee is not weak, but they think that "These devotees, they are weak. They cannot do any materialistic work. They cannot build skyscrapers. They cannot build a subtle machine. So they have taken to Kṛṣṇa consciousness. They are chanting Hare Kṛṣṇa." You see? They think like that.
