Firstly, I'm very sorry that this happened to your cousin. This elduh had NO DAMN right to make this judgment call!
Secondly--and this is a SIDEBAR point--, WT has influenced (and more than likely under-the-cuff mandated) elduhs to act like "Spiritual Policemen"* even when it comes to household situations. A couple of decades ago, there was a sister [I'll call her "Q" (who at the time was PIMO but is now POMO)], who didn't get to attend KH meetings as often due to not only being Mentally Out but primarily because of her job schedule. Getting to the heart of the matter, 4 out of the 6 cong elduhs and 2 MSs noticed this. These jamowckers came to Q's home (she lived with her widowed mother and 2 siblings), and tried to convince her mom to "KICK her out of the house"! 😨 After a large argument between the family and these elduhs, her mother plus 1 of her siblings under pressure from this group of men, made arrangements for Q to leave. They claimed that Q was a "spiritual danger" to her family. Thankfully, Q had her job and her own car. So, she after 2 weeks, ended up living with an NI (Never In) relative until she can find her own place. A few months later, Q finally woke up to TTATT and eventually left The Borg. Although she went through all of the above, I say: "GOOD 4 HER!"! 👏🏻👏🏽💯
*Spiritual Policemen": What GB1.0 (Sidlik, Schroeder, Swingle, etc.) told in talks and within some past literature that the BOEs plus MSs are not and are not to become towards the flock. It was mentioned that family heads (males and females) and single adult dubs are to make their own decisions based on the Bible and the literature (at that time) when it came to problems/issues. The elduhs are not to be called for everything and not to involve themselves in everything/aspect of a JWs life. Now, with GB2.0 at the helm, things are WAY DIFFERENT! 🤨
