Just FYI... drawing a black and white is exactly what you did here. This is the standard way of framing the question of therapy validity. Therapists are either good or bad, ethical or not. Clients are resistant or open to change, lazy or willing to "do the work", yada yada yada.

This is a red herring. You have to look at the relationship itself to see why it is often destructive and exploitive and abusive. All therapy is unethical in some ways. All therapists harm in some ways. Even therapy that seems to be going well might be digging the client into a hole of external validation-seeking, loss of autonomy, skewed perspective on relationships, etc.

Seems the reason people want to get into the profession, even knowing the dark side, is precisely because of the good therapist/bad therapist binary. Hey, i'll just be one of the good ones.
