My brother is 2 years older than me . he always been an asshole but we've had our positive moments . like when i saved him from falling out of a window by barring his legs inside of a sill , or when i stood sideways i grabbed his arm to pull his head out of river on a white water rafting trip , or when i didnt kill him after he shoved my neck into the hood of my car after jumping his battery over i dont know why . he has a 100k/yr job running medical lab tests and just bought a new car . 14 months ago his best freind got into a car wreck and didnt go to the doctor , died from internal bleeding 2 days later bro found him dead on the couch , he was a persistant felon that spent most of his life in prison .. 6 months ago he came home to his girlfriend od'd on the couch . he got her onto heroin and she had a bad reaction and didnt want to go to the hospital because they would see the tract marks on her arm . he's horribly depressed but he made this hell for himself . recently he's been staying at our parents while working a contract , he got drunk and did drugs and wrecked his new car and tried to run from the police during the sobriety check . apparently he completely lost his composure with my parents today and is suicidal. he has had so many chances . should i suggest to my parents (70+ yrs) that they need a restraining order or can i get one on their behalf ?
