It is not Krishna who killed Narakasura - it's Satyabhama, His wife

One of the most famous stories of the Deepavali festival is that of Narakasura. Narakasura is the son born to Varaha (the 3rd incarnation of Lord Vishnu in the form of a wild boar) and Mother Earth (Bhudevi). Mother Earth fell in love with Varaha; so they got married and had a son named Naraka. When it was time for Varaha to go back to his celestial abode, he blessed his son with power and a long life as requested by his wife before leaving them both. Mother Earth did not have much time to look after her son either. Due to an unchecked association with a demon named Banasura since childhood, Naraka grew up to be an evil demon as well and he became known as Narakasura thenceforth.

Not satisfied with the powers his father had given him, Narakasura prayed ascetically to Brahma for such a boon that only his mother should be able to kill him, as he was confident that a mother would never kill her own son. After Brahma granted him the boon, Narakasura proceeded to conquer many kingdoms. He also kidnapped 16,100 princesses from these kingdoms and imprisoned them.
When Narakasura’s long evil reign was almost over as per Varaha’s blessings, Lord Vishnu decided to come to earth as Krishna and as his wife, Mother Earth appeared as Satyabhama. When it was time to fight with Narakasura, Krishna coaxed Satyabhama to come along with him as he knew that it was only she who could kill him. As she was enraged to hear Narakasura’s ill treatment of women, she agreed to follow her husband to war. Krishna fought gallantly against the demon’s soldiers and defeated them, but he couldn’t defeat Narakasura.

Narakasura unleashed a thunderbolt weapon against Krishna, hurting him slightly. Krishna immediately seized this chance and fainted in pretension, to provoke Satyabhama to fight. Satyabhama got furious seeing her husband being hurt and she took up Krishna’s weapons. She doubled her attack on the demon king and finally killed him. Just before his last breath, Narakasura requested a boon from his mother, Satyabhama, that everyone should celebrate his death with colourful lights. Everyone who was oppressed and imprisoned by him celebrated their freedom on this day as Deepavali. (In North India, the following day is celebrated as Diwali, commemorating Ram's coronation day).

Krishna did not feel challenged at all by his wife’s bravery and victory; he was all the more proud that his wife killed Narakasura. Let us all take the example of Satyabhama being heroic for the sake of love, and of Krishna for not being puffed up with male ego, simply to take the spotlight for himself.
