I have done this in the sense that I have never reported on anyone. And I was silent for a very long time about what has happened to me. It did come up in therapy. My shrink talked about the famous essay by Ferenczi that talks about "identification with the aggressor" and the way that especially children accommodate their abusers. I read it and found some things that helped me explain what I had done in various situations and why. Since this essay was ground-breaking, I take it as definitive in the sense that this kind of response happens a lot so it put me at more ease and I didn't blame myself for doing what I had done up to that point. But it did make me feel more comfortable with becoming more clear about how complicated and wrong the situations were so I was able to break away a little bit from the way I had been dealing with it.
