Profit Incentives. By nature humans are a contradictory creatures capable of both good and evil. In the medical field the evil part gets maximized because they see so many patients they get lazy and lose the desire to do good and they also lose sensitivity against avoiding evil. So what happens is they will lie for more money. Very common.
Dehumanization is a term about getting rid of the evil and the good because being human is about both evil and good. That's not what the parent is doing. You're the one interpreting humanity through a dehumanizing lens. You should expect immorality and incompetence from humanity by default. Any other view is dehumanizing.
