Kids have to be pushed to clean up after themselves, to be polite, to mind their manners. Wild children will most often eventually learn to fit in and stay there, but they will take torturous paths to get to that point whereas Stepford children are likely to look great on paper but grow up resenting the people who took away their autonomy for appearances' sake.
Neither extreme (Wild/Stepford) is a good thing, Wild Children tend to get into and cause a lot of trouble, and end up missing out on opportunities both personal and interpersonal due to their lack of grounding and inability to meet societal pressures/standards.
Stepford kids (at least in my anecdotal experience) tend to end up rebelling hard, or developing a need to hide their flaws and issues out of fear of reprisal, and sometimes end up having huge breakdowns because their fundamental emotional and developmental needs aren't being met.
Sounds like Wil was forced to be a Stepford child, and this is the consequence of that, not to mention his mother both abusing him and allowing him to be abused by other people while wringing every penny she could get out of him in the process. That's pretty shitty.
