I spoke to a family member tonight who's worked in maximum security prisons for years and I asked what an inmate (in Canada) has to do to get put on suicide watch. He said they would have to get a psych evaluation, not that they necessarily attempted it, could be used to watch him 24/7 or to keep a person separate from other inmates in this case because of the child factor. He also said with psychopaths, after they're done doing their damage/crime and get caught they fall into a deep depression called 'zero state'. They get severely depressed while incarcerated because they're not able to do their manipulating and other deviant things they do. BBM, just thought that was interesting to know.
That is true - some experts describe zero state as a quiet rage rather than a depression. The psychopath is furious that they can no longer manipulate others, and they are terrified that everyone will see through "the mask".
