I believe it does not matter what the therapist thinks or feels about what a client does. It is not the therapist's life to live or not live, nor anyone else's for that matter. ( I have had two close friends commit suicide in the past 5 years - one quite recently - lest anyone wonder if my approach is tinged with lack of knowledge of any sort about the situation.)
I would think it might make some therapists angry, some sad, some will blame the client, some will wonder if they could have done anything, some will just go on with their lives, and so forth - just like real people.
Why would it matter what it means to the therapist?
