I don't think there's a "proper framework" for that because it's not valid reasoning. This viewpoint disregards the flux of the brain in favor of a vague, static "psyche". The brain is plastic, vulnerable, and swimming in a hormonal soup that it's also responsible for regulating. It can fall into feedback loops because of this. E.g.: stress damages the hippocampus, the hippocampus loses some capacity to mitigate stress, leading to more stress that damages the hippocampus further. In that hippocampus example, we know that SSRI drugs can reverse this damage. On the other hand, they can also lead some patients to experience increased thoughts of suicide. An anxious/depressed mind can become a suicidal mind or a healthy mind in reaction to the same stimulus. Things can happen to healthy minds that send it to those corners as well. We can't just assume that someone who died of suicide was on a fixed track to get there or that their advice from a healthy mind lead to an unhealthy mind.
