I think what Torn was referring to is how many IC's are not pro-marriage and actually encourages the WW to do whatever is necessary in order to find her happiness out there. This is not what a WW needs to hear from a professional. She's not logical, and she will take those words and run with it, to break vows, ties/bonds, commitments, and relationships. She'll hurt whoever stands in her way. In the WW's mind, rather than hearing how she can work through her issues, she's hearing encouragement to continue living a wayward lifestyle. Since the WW already blames her H for all her unhappiness, one of the first things she'll do is break up the M. In her viewpoint, it takes care of her problem of unhappiness.
It's incredible to me (as someone who works in the field) how quickly people will tell you to just up and leave an unhealthy, dead-end relationship. It's almost like we as a society have put WAY too much emphasis on the importance of R for happiness, to the point that when someone is unhappy, it's the easiest target. [Don't even ask me how WW reacted when I said, "W, you say you were unhappy because of me. I say you were unhappy and I happened to be standing next to you."]
OK, ICs do have an ethical responsibility to provide the treatment (or advice) that is in the best interest of their client, as an individual human who may or may not be in a R. And there's risk involved in telling someone to stay in a R if there's a concern that they are being mistreated/abused. But ICs can only work with what they're given, i.e., what the WW is telling them, which is probably total garbage. Net result: fanning the flames. [Long before I knew about DB and WW, my W was saying things like, "IC has been teaching me to listen to my feelings." Barf.]
The point is, if WW can manipulate her H, she can certainly manipulate her IC.
