That any adult thinks they know what is for any other competent adult "own good" is horrifying to me. It is condescending and patronizing and any therapist who thinks in such terms is lying either to themselves or the client or both.
I would interpret such to mean the therapist was incompetent and rather than admit it - put the blame on the client to make the therapist feel better. Therapists are not better humans than anyone else and are just as likely to label, blame and shame the client to avoid responsibility as any one else.
