To me, this story suggests that it was not the other women going to the water that were judging her, convicting her, and pointing out her sins to her, but rather it was what was deep in her soul, her feeligs of being unworthy, that stopped her from joining in. And, it was the power of redemption (which came from Christ) that was able to lift her from this place. Something about not throwing stones from glass houses comes to mind. So, these people of holy spriit did help her to change her ways, but they did so without muttering a word of ridicule or condemnation. They did it by example, which opened her to what Christ had to offer her. At least, this is how I see it.
