That dynamic is called Karpman's (Drama) Triangle. I would love to say that I invented this dandy little concept. But it's actually been around for a long time. Since 1968 actually. It was invented by Stephen Karpman, a student of transactional analysis, and was called Karpman's Triangle or the "drama triangle". As anyone who has ever been in this dynamic can attest, it is definitely drama-producing! None of the roles are actually healthy and the goal if you find yourself in this situation is to move as much to the middle as possible, not aligning yourself with any of the positions.
Despite what they might say about how they feel in the moment, be aware that the Victim role is not actually a person who is being harmed, it's a person who is emotionally invested in looking like they are being harmed. It is also a person who does not want to have to take responsibility for helping themselves out at all. They want everyone else to come and rescue them. They often complain to others that they are being abused, oppressed or victimized and that they cannot do anything about it. They are likely to block any suggestions that they can change their circumstances by saying things like "that won't work" or "I can't do that because _______". In reality they are invested in not acting as agents of change for themselves. These roles are usually learned in childhood by having them modeled by a parent, so if your mom played the victim role, you may find yourself repeating that pattern. Interestingly people who tend towards the Victim role will seek out Perpetrators if they don't have one in their life currently. Unconsciously they don't feel comfortable not being in that position so they have to create it. Sometimes what is at the bottom of this is a history of having been rewarded for being helpless and small and dependent as a child. This creates a conflict where they feel that in order to get their needs met they cannot actually do things for themselves or "grow up" and act as mature adults. They have to find ways to get a Rescuer to save them from a Perpetrator because they were trained never to "rescue" (or take care of) themselves. Remember that all of this is happening unconsciously so no one is actually "asking" to be victimized while being aware that is what is going on. The Victim thinks that they are just in a bad spot and can't seem to find a way out until they find the magic Rescuer who rushes in to save the day. I am not in any way saying that we cannot be compassionate about someone whose life is not going the way they want it. I am also not saying that whatever is done to someone in the victim role is acceptable. I am not victim-blaming. I am, however, saying that everyone has some power to make some changes in their lives and that victims often have a hard time seeing this.
Rescuers are compulsive helpers. This is the classic Martyr role. Rescuers are so inclined to rescue that if they see a person in need and don't rush to their aid they feel terrible. They feel compelled to help others and don't see that this can deprive the Victim of learning to do for themselves. It also allows the Rescuer to focus on other people, which tends to be much more comfortable for them. They derive a lot of status and satisfaction from taking care of others and they don't have to face any of their own issues. Al-anon was originally developed for Rescuers and one of their mottos is "keep the focus on yourself (not the Victim!)". However just like the Victim, Rescuers are usually totally unaware that their role serves to keep them from dealing with their issues since it is entirely unconscious. They just tend to think of themselves as "good" people in a world where a lot of folks need a lot of help! They were often raised in families with a Victim and they learned early on to care for the Victim, which made them feel better about the situation of the family.
The Persecutor tends to come from families in which one or both parents were bullies. They have seen this behavior modeled and follow along, blaming others, trying to control them, being critical, rigid, angry and often acting (or at least feeling) superior. The Persecutor thinks of themselves as "realistic" and "hard-nosed" but typically not malicious. They feel that the Victim and the Rescuer are naive and don't realize that it's a cold world out there and people are going to take what they can. It's kill or be killed and they plan to be on top. They view Victims as people from whom things can be extracted-- work, love, sex, money, status-- but not in a mutual way that cares for both people. When they have gotten what they need from others they may discard them. This can come in the guise of "realizing it just wasn't working out" because they have detected a "fatal flaw"in the person. As parents they tend to want to "toughen-up" their kids and may make kids feel like no matter what they do it's not good enough. Or they may blow up and rage at the kid(s) and then blame the kid(s) for causing them to get angry. They may have unreasonable rules that must be followed and refuse to allow kids (or partners) to negotiate on their own behalf.
While we often learn one of these roles more deeply than the others in our families of origin we can also switch roles at any given time. A Victim may see an opportunity to retaliate against someone who has been a Perpetrator and take it, often in a passive-aggressive way that is not easy to detect. In this way they temporarily enjoy being a Perpetrator while maintaining the image of the Victim. A Rescuer may get tired of taking care of others and experiment once in a while with throwing up their hands and acting like a Victim. A Perpetrator may find that by occasionally acting like a Victim they can avoid taking responsibility for bullying others. However if we do this "drama triangle" regularly we do tend to gravitate towards one position based on our early experiences.
Again the goal of emotional health is to not enter into any of these roles. Each of us has the capacity to be passive and dependent and wish that some fairy God mother/father would come along and take care of everything for us. And each of us has the fantasy of being the knight in shining armor riding in to save someone. And yes, even if we often don't like to admit it, we can also all be the kill-or-be-killed person who steps on others to get ahead and gets a thrill out of winning, even at any cost.
If you suspect that you came from a dysfunctional family you may want to spend some time honestly asking yourself whether or not your parents show up in this triangle. If they do then you can ask yourself do YOU show up? And where? And what work do you need to do in order to move more to the middle? Victims need to learn to do for themselves and to feel pride and competence by growing up and owning their own power rather than wanting others to fix things. Rescuers need to ask themselves how they are avoiding their own pain, anxiety, sadness, grief, etc. by focusing on others all the time. And Perpetrators need to learn to be vulnerable and realize and express their own desires to be dependent sometimes rather than to only feel safe when they are lording themselves over others.
Therapy can be a great way to learn about the Karpman triangle and other dysfunctional dynamics. It is also one of the best ways to change those dynamics. You don't have to stay stuck in the Drama Triangle forever.
Wishing you health, happiness and balance in all of your roles in life,
