In the meantime Jalandhar went to Parvati disguised as Lord Shiva, but was recognized by her. Being enchanted by the beauty of goddess Parvati, he looked at her with his evil intentions, but was immobilized by her wrath. Goddess Parvati then went to Lord Vishnu and narrated the whole tale. She requested Lord Vishnu to go to Jalandhar's wife in the guise of Jalandhar and act in the same way.

This sounds injustice. How to justify?
