i genuinely think my brother has to die i don’t think there’s any other option

he’s 32. severely autistic schizophrenic and bipolar and psychotic (i know) my parents are immigrants who don’t understand anything about mental illness and we’re in denial for years. after all of his violence and terror in my house growing up i finally escaped but it’s like he’s still here. he has gotten help after assaulting multiple minors and women around him and having to beat his criminal case but now after getting medicated he just eats and walks around like a zombie attached to the hip by my mom (his caretaker). he’s now well over 350 pounds and still kicking but a like a husk of himself thankfully. the only problem is is that my family genuinely has no plan for him literally nothing. my mom is convinced she will marry him off by offering some woman money as an exchange to be his caretaker but she knows damn well that’s not gonna work. NO ONE wants to take care of his big ass and i just know my mom will try and guilt me and my siblings into it and we will all say no.. he’s so cooked and we all know it it’s like watching a train crash in slow motion. due to his schizophrenia and criminal record no facility in our area wants to take him and he’s as fussy as a 5 yr old it’ll be mission impossible to convince him since my mom can’t stop spoiling him and defending all of his actions. i cry and cry about this and yet i feel such apathy and just think it would be best if he just die. i really think sometimes if he just died i wouldn’t be so fucked up and honestly i think id feel a wave of relief. he’s a genuine menace and a burden to us and society.
