So this new update frankly left me with a serious WTF, I mean look the father was poor than he hit rich, also for some unknown reason he is obsessed with getting his old house back, and now he is acting like a big bad crimelord bring some thugs to force his wife to sell the house, and have his son beat up by thugs, but the thing is at this point its game over for him, all they need to do is go to the cops with the son that got beat up near to death and he get arrested and sent to prison, the guy is obviously not smart enough to have made THAT much money that he can just silence the justice system.
See the thing is using thugs to force people to do stuff like that only work if 1) the people you are trying to blackmail can't go to the cops because they themselves did something reprehensible, which isn't the case here, or 2) you are a career criminal that doesn't have any legal persona to get punishment on, which also isn't the case here.
Also people doing this typically understand that if you push too far the people you are trying to blackmail are going to snap, now the father had his son beat by thugs, something so blatantly illegal and something bad enough that it would drive his son to decide to go to the cops, at which point its so easy to prove by the fact he left with a legal document on the same bloody night, so he should be promptly arrested for his crime.
Frankly their are a ton of steps that should have come before that point, including breaking windows, damaging the cars, putting pressure in various indirect ways, not jump straight to blackmailing his ex-wife and beat up his son.
