Crusader, wow.
At first, I was going to discuss the issue of psychopath/Christianity/demonic but...I decided to reread all your posts. I'm shocked at what you've told us. Like wow man.
Crusader said: because i dont have to be attached but as it is my older brother its been very interesting trying to battle of the constant manipulation of him trying to gain control somewhere in my life. (i have alot of money comeing my way which he knows about)when we where younger and i was less wise, we ended up in a fist fight when he tried to control me and i choked him out cold so he is careful how he tries to manipulate me. I have no doubt it is demonic i only use todays terms as most people have an idea of the behaviour and yes he has 45 years of destruction behind him, he used up all of his exs and left them with nothing.
First things first. You can't control your brother. Your brother needs to have the *desire* to be set free. What actions/discussions leads you to believe your brother *wants* to be set free?
Second, your actions need to be thoroughly covered in love. Choked him cold? That's not love. I hope you recognize this. You don't need to be around him. Jesus ran away but eventually He died in utter selfless/unconditional love. Is that your path? I doubt it. but if you feel you need to remain in the situation with your brother, these actions need to stop. You can't say you love your brother while you choke him out, that's called hypocrisy...
Might I suggest, you disarm. If your brother attacks, disarm him. If it does get physical, you subdue him. Find a way to totally disarm him. Sit on him. Do something. But...as this happens, I suggest that you pour your love into him. Saying things like, 'Brother, I love you. But you need to stop this behavior. I care about you but you are hurting yourself and everyone around you. etc'
I've had a lot of crazy situations happen in my life. Dealing with it all, 'in the Christian' way, is...complicated. The Holy Spirit has the ultimate leading. God might be saying that you need to leave, that you currently *aren't* equipped for this. If you and your wife are meant to be as a team, talk situations out with her. Together, the Holy Spirit speaks clearly.
Please remember the first piece of advice. He needs to want it. Does your wife agree that your brother wants help? If not, then...it's not the time to stay close.
If your brother really wants help then his actions should clearly demonstrate his struggle. On the other end, keep in mind, if his actions go to far, he needs to be turned in to the authorities.
Meet him in jail, 'brother...your actions put you here.'
This situation is complicated. My answer isn't fullness. But these are general principles that I've found to help me hear (and act on) the Holy Spirit in these situations.
I will be praying for your wife, you, and your brother.
