“The demon harasses the devotee, even though the latter may happen to be his kin. Although Prahlada Maharaja was the son of Hiranyakashipu, he was nonetheless persecuted by his father; although Devaki, the mother of Krishna, was the sister of Kamsa, she and her husband Vasudeva were persecuted only because Krishna was to be born of them.” (Shrila Prabhupada, Bhagavad-gita, 4.8)
