Is my client’s husband one of these people being cultivated as a troublemaker?

This is the case and now you see the problem more clearly in what you are up against and she faces in trying to cobble together a minimal life without constant threat and fear. It will not be possible around this individual. You have healing underway for him but he is among those hardest to reach because of the level of corruption involved. This you see in his acting out irrational behavior as he recounts to her the many fights he gets involved in and the entanglements with the police, and so on. He simply cannot control himself and that is a hallmark of the psychopaths who are being manipulated through mind control to weaponize them deliberately against any and all the interlopers can.
