Hansel and Gretel's revenge

As you recall, it was a time of great famine in the time of Hansel and Gretel and the step mother persuaded the father to abandon the children in the woods so the wife and husband wouldn't starve.

So, the kids get lured in by the witch and eventually kill her. Then what? What do the kids do? Do they return home where the step mother is still living? Do they get Dad out from her influence? Do they move on? Do they open a witch extermination service? Do they get arrested for murder?
