Update : AITAH for "terrorizing" my brother making him live in his own filth?

Hello everyone, I considered leaving the situation with my brother at the original post, but this post has blown up and is being covered outside of reddit so I figured I should tell you guys what has happened.

To start, I know a lot of people seemed incredibly perplexed I even allowed this. To this all I can really reply is that I grew up in a very toxic environment. They are Mormons, and not the modern kind. When I was a kid, I was not allowed to wear pants. In my childhood if you asked a man to clean you would be looked at like you were insane, and if you got mad at a man being messy it would even be implied you could possibly be corrupted spiritually for attacking the original design. Obviously after I left the church, I understood that things are different, but I am not as healed as I thought. I obviously need a lot more therapy. I also got a few posts asking why I didn't include that I am autistic in my post, this is just because it is not relevant.

The actual update: My brother is MIA. For anyone who missed it the day after that post I came home to a trashed house and a glass of milk spilt on the floor that had obviously been there for a while. I lost it and lugged the milk jug at his head (thankfully missing) and screamed at him over and over to "get out". He tried to square up to me, but I screamed so loud it was hard to talk the next day. I think he got the hint then and took off (almost ripped my door in two doing it, I had to replace a hinge) I know some people wanted to me to sue him but during this whole situation I was confronted with a health scare (just some weird looking moles but I am still worried) so I do not want to deal with that. He left, get this, and went to the house of his 19 year old girlfriend. Apparently, he met this girl when she went to the bar for her 18th. I had no idea this was going on but all my brothers did. To recap. he had a baby with his GF of 8 years, THIS MONTH. I told them all to fuck off, when mom messaged me crying because "no one knows where your brother is he just left with some girl" I told her I do not care. I did (call me crazy) message the girl to tell her he is bad news but she called me a crazy c%n and blocked me. I also messaged the girls mom who seems worried but basically said she cannot do anything because her daughter is legal. I guess they took off and skipped town and will not tell anyone where they are, outside of worry for this girl I do not care. I am too busy chilling with his EX and my wonderful niece. I am going to take care of my health and focus on my life.
