I was thinking that your brother sounds kind of narcissistic??
it's all about him and what he wants to do - no one else is important or even considered??
Or he definitely has some other serious issues that need to be professionally addressed.

If he hasn't even apologized {a true apology} for his horrible behaviors and continued bad choices- I would be very tempted to cut off contact completely until proof of repentance and changes can be shown.

Plus all of his illegal & violent actions!
