IMO transference is necessary for the therapeutic process. Perhaps it is this fact that makes it so difficult for those whose trust has been smashed by abuse, as they don't have any good, trusting relationship to transfer onto the Therapist?

I wouldn't want the bad transference to happen, but if noticed, it can be worked through. (For example, you yell at your therapist because that's the way you handle someone in your life. The therapist needs to show this to you while also not accepting this behavior from you.)
