As far as people are enslaved by satan/sin, he can use his slaves to do his evil works.
This is why GOD's destruction of cities and people weren't restricted to adults in the cities.
Don't let satan make you think he does not use children for witchcraft and other evil.
The battle is not against flesh and blood. Many children into witchcraft and other evil don't know what they are doing
