I think to be a part of this field in a truly ethical way would entail being brutally, unflinching honest about the damage people in this field have done to people who have come to them for help, and the ways in which the structure of the profession, the training methods, theories and their inadequacies, and the ethics and complaint processes, hide and even promote what is happening and will continue to happen. If you can do that, then maybe go for it. If not, I think you're fooling yourself, doing what you want in spite of the ethics, or both.
