It's Jesus Christ who stepped on the Serpent's head,
by dying on the cross and giving His own life for His people's sins.
He defeated the Serpent by paying for their sins for them.
That pic of a female principle doing what only Christ had and could have done is "satanic grooming" in and of itself.
He's the only one who was without sin,
the spotless Lamb of God.
His offering was by its spotless nature effectual in taking the place of sinners.
For that reason,
He didn't need any "help".
God the Father provided only that Lamb for the sins of His people.
