Power can corrupt when someone is looking for power and when they start liking it, so they will go out and try to think they are better than other people.
Explanation:
The balance of power between the characters changed because when the man was stuck in the well the children thought they had more power over the man in the beginning of the story, but at the end of the story, the man in the well gained more power over over the children when he was making them scared because he knew their names which frightened them.
I would say, because these men are hunting slaves for money. this is greed and it is wrong. and then to go home and pray with their families. Kinda like thinking about a police officer getting arrested. ( if that helps at all)
