I can gauranty you your brothers are scary to you, but, to a guy who has been in prison they are probably a joke. Not to mention, if you love your brothers why would you want to put them in harms way? I would do what was suggested by somebody else and call the police. If this guy is capable of turning on the police and beating his wife, what makes you the exception? Just saying...Chose your battles wisely. Hope it works out.
