Dealing with the anger after

How do you deal with the anger after? I've had no contact in 6 months but I'm still angry. And I still have this great desire to GET EVEN, which is impossible. For those in similar situations, how do you feel about the narc continuing to spread his "love" all around to other perhaps unknowing victims? Is there not some sisterhood we all have that we need to protect these poor women? I am minding my boundaries mostly because I have to for confidentiality but he continues to thrive and prey on countless other women.
