Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 27


एतदर्थो हि लोकेऽस्मिन्नवतारो मया कृत: ।वध्या मे धर्मध्वजिनस्ते हि पातकिनोऽधिका: ॥ २७ ॥


etad-artho hi loke ’sminnavatāro mayā kṛtaḥvadhyā me dharma-dhvajinaste hi pātakino ’dhikāḥ


The very purpose of My descent into this world is to kill such hypocrites who pretend to be religious. Indeed, they are the most sinful rascals.


Lord Balarāma was not prepared to overlook Romaharṣaṇa’s offense. The Lord had descended specifically to eliminate those who claim to be great religious leaders but do not even respect the Supreme Personality of Godhead.
