NO, I would not go back for the sake of those seeking reinstatement. If I cannot get TTATT to them outside the Kingdom Hall, I can't see how going to the Kingdom Hall would make a difference. There, they will be shunned and I would either sit with them and be shunned or sit elsewhere and have to join in on the shunning of them.
FORGET IT!
Edited to add:
And letting anyone know, "I'm just here to support 'Suzy.'" will just hurt 'Suzy' on her reinstatement. She's hanging out with the likes of you, someone who is not regular and not intending to be regular. If 'Suzy' wants to be reinstated, she can't be your friend inside the Kingdom Hall.
