I fully agree with this. Jack is fucked up beyond mortal comprehension and approaches the world from some psychotic angle we couldn't begin to guess at. Still, though, you'd think he'd develop a learning curve of some kind. You know, "Hey, when Suzie started acting weird and doing crazy things, she ended up committing murder. And then she died. That was all bad. Owen is acting weird and doing crazy things. Perhaps I should handle him differently from how I handled Suzie. Maybe then bad things won't happen." But nope. Apparently not.
