Jesus said to love your enemies.
He did not say to destroy evil.
In fact he says not to resist evil.
The dualistic mind set which sets up a battle between good and evil is not the way of Jesus nor is it the way of God.
The parables of reconciliation :
the lost sheep, the lost penny, and the lost son
show that God seeks redemption even to the last one.
A more modern example of this is the story of Dorian Gray who corrupts himself completely through the temptation of eternal youth. At the end his dead body resumes its corrupted state and the picture reverts to its original youthful image.
We are not told what becomes of the soul of Dorian Gray.
I believe that his soul is forgiven and reconciled with God.
Because in my experience God punishes no one.
He seeks redemption to the very last one as we are taught in the parables of reconciliation.
God understands everyone, even those we call evil.
So evil is not to be battled against and destroyed.
Evil is to be forgiven and reconciled to God through love, the unseen hook.
