Is it permissible to distance oneself from a brother who practices masturbation in front of his family, curses and uses inappropriate language, instigates problems, and seeks to seize the house?

It is permissible for a mature,成年 woman of sound judgment to reside wherever she wishes, provided she is safe from temptation and free from suspicion. There is no blame upon her for leaving the home to avoid the harm of her brother, who is committing a forbidden act (masturbation) and openly displaying it before his family. This is a reprehensible insolence and lack of modesty. He must be advised and reminded of Allah, and assisted with marriage through whatever financial means are available, and a righteous woman should be sought for him.
