Would you say that psychological disorders born out of strenuous situations end when that person is no longer in that situation? How long does PTSD last? Does it stop being an issue after 2 years? What about depression? When does it end? From what I understand depression works by episode. Do you believe it unlikely that this person may have seen fine for the first year and then developed a depressive episode later on? Seeing as how much you understand of psychological illnesses, I was hoping you could clear these up.
Furthermore, does your stance apply to every situation regarding such situations and suicide? For example, say a soldier develops PTSD while in Iraq. If they commit suicide 2 years later, can their experiences throughout the war no longer be blamed for their suicide because of how long it has been? Or do we blame his wife for 'failing' him even though she may not be mental health professional?
Say a child is molested by his uncle for 3 years and commits suicide 2 years after the last incident. Did the parent fail the child or does the child's suicide lay squarely on the shoulders of those who actually caused him to have such feelings in the first place?
Because I know for a fact that you won't have a consistent answer to these questions, it seems to me like you're trying to scapegoat pretty much everything in this kid's life except for the very system which incarcerated him, denied him a speedy trial, and then basically forgot about him until the public outcry was way too much. That's just what's obvious to everyone in this thread though.
