The build up of the current situation:
My brother (about to be 21) rented a room from people he knew and had a friend living in another room they were renting too. Brother sees this as a good gig, likes the fact is around people he already knows. This is where it gets frustrating, though. My brother managed to get a good job and saved enough money to pay his renters **a year** in advance. Okay, that's meh, but you're doing fine and like the place, so you do you.

 Couple months in, my brother starts to realize that the home owners are assholes. They treat their oldest kid like shit emotionally and degrades him. The man of the house would threaten friends the room renters would bring over (my brother and his friend). I spent the night there and the man was up until 3 AM, drinking to where he couldn't stand up, blasting some weird indie rock band. He also managed to break one of the renters new guitar stand when attempting to get himself up.
  I could understand wanting to leave this situation. My brother clearly hated the environment and I didn't blame him, or his friend who moved out after the home owners yelled at the girlfriend for taking 2 showers (mind you, she is paid for by the boyfriend who rents the room and part of bills). More months follow my brother doesn't contact our parents at all. I come to learn he has been complaining to my grandma and just getting food and stuff from them. I find this weird because he always tells me that my parents don't care about him when all they did was give him advice because my father wasn't happy this his son was being taken advantage of.
  10 months in and my brother doesn't have a job, no car, nothing. He claims about not having a job because every business is too far, but he lives 2 blocks away from a food 4 less and jack in the box. Public buses also exist. He mopes for a couple more weeks and then suddenly starts going out with friends? He is eating the home owners food, living there since he paid a year in advance despite him hating living there. I get frustrated with this because my brothers owns 5 gaming consoles. And more than 100+ games combained for each console.  He complained about having no money while he stays at the house and plays games, eats, or sleep.
 Coming onto this month my brother talks to my dad and my father lectures him saying he can come back whenever and I full heartedly did not agree with this because my brother took no chances to get a job, sell anything to get money or a car, didn't do anything. Complained only to my grandparents but he wants to come back with his family. To do what? He doesn't go to school either, dropped college. Last time he was here too he didn't clean, didn't go out to try get a job and my parents didnt like that  but here he comes again.
I havent talked to my brother in 3 months because of personal reasons but before this we were super close for siblings and knew what was going on with each others lives for the most part. But i don't like him any more, even more so because of the situation.
AITA
sorry if it's all jumbled, frustration is making my thoughts messy
