Sometimes the TTATT is like a,... well,.. a malignant tumor that has wrapped itself around a person spinal cord to the point where surgery is not an option as it could paralyze the person. I think what determines the option for telling them or not is just how bad the tumor is entangled with the cord and if the health of the person (mental health) can take the tedious surgery to remove the tumor.
I think there are Jws that I know that would not be able to "take it" and would crash and burn upon trying to hear the TTATT. A few of them, if handcuffed to a table, would beat their head against the table to try to knock themselves out before listening to TTATT.
