Is it permissible to cut ties with a son who filed a lawsuit against his father for beating him due to his drug addiction and homosexuality?

A son who abuses drugs and engages in homosexuality commits serious sins. Drugs are evil, and every intoxicant is forbidden. Homosexuality is the act of the people of Lot, for which they were severely punished. It is permissible to abandon such a son, but the priority is to consider what is most beneficial. If abandonment would lead to greater corruption, then it is better not to abandon him, but rather to try to win his heart, advise him through those he is likely to respond to, and supplicate frequently for his guidance, for a parent's supplication for their child is answered. Hitting children is not an effective method of upbringing, especially if the child is an adult, and hitting out of aggression is forbidden. A parent should not expose themselves to legal accountability. A son suing his father is not considered disobedience if the father is not unjust. Parents should choose a righteous environment for their children and raise them on goodness and virtue from a young age.
