Any psychologist with a clue about anything knows that it is an absolute waste of time to try and help someone who genuinely doesn't want to change. You can't just put someone in a "healthcare program" (whatever that is) and expect them to get better. They have to WANT to be there. And if they truly do desire change, then they've already made the monumental breakthrough of realizing that their problems aren't with the world, but rather with the way they interacts with the world.

Someone intent on mass-murder does not have those thoughts. They just don't.

So, I'm wondering how Oskar expects these "health care programs" to reduce mass-murder. And the only explanation that fits...is sorcery.

If that's wrong then Oskar, or anyone else, is welcome to posit an explanation for how a government funded social welfare program is going to change someone who doesn't want to be changed.
