Why did Krishna order His Narayana sena to fight on the side of injustice?

Smt. Lakshmi Lavanya K asked: Why did Krishna order His sons, grandsons, relatives (Narayana sena) to fight towards injustice? Weren't they devotees of Krishna? Thank You Swami.

Swami replied:- The Narayana Sena was the army of Krishna. Moreover, what is the significance of relationships in the eyes of Krishna? In the eyes of Krishna, relations and outsiders are one and the same. The distinction between relatives and outsiders is in our eyes only. Being relatives of Krishna, they need not be very high devotees of God.
