Suppose a doctor, a doctor goes to a patient. He is under convulsion, he's talking nonsense. That does not mean he will refuse to treat him. He's treats him as friend. Although the patient calls him by ill names, bad names, still he gives him medicine. Just like Lord Jesus Christ said that "You hate the sin, not the sinner." Not the sinner. This is very nice. Because sinner is illusioned. He's mad. If you hate him, then how you can deliver him? Therefore those who are devotees, those who are really servant of God, they have no hate for anyone.
