Cersei Lannister may seem like she has it all: unbridled brutality, a mountain of a protector, disfavor in the Realm and a growing list of enemies she's collected along the way. After all, she's just destroyed her enemies in one fell swoop as she blew up the Great Sept of Baelor. Although Cersei seemed to have finally served her sweet revenge, she comes to discover that bittersweet aftertaste that just won't quit.

Cersei soon found out that the fleeting rush she got from all the carnage and destruction (just a few of her favorite things) gave way to a mixed bag of emotions; on the one hand she finally got her seat on the Iron Throne, but on the other hand, she had lost all of her children in the process.

Apparently, Cersei's conflicted feelings on the subject of revenge are not unique to her.
A recent study in the upcoming edition of the Journal of Experimental Social Psychology found that the emotional consequences of revenge "are a mixed bag, in that we feel both good and bad when we take revenge on another party."

Take the good: we love revenge because we punish the offending party. Apparently, the brain areas in charge of making crime and punishment judgments overlap with areas that process reward, which explains the pleasure in punishment/ revenge.

But then there's the bad: it reminds us of the original act. To put that kind of pain it in context, think about the revenge your stomach exacts the morning after you eat an entire pizza. We've all been there.

In fact, just ask anyone who has slashed their cheating ex's tires. Or take the story recounted by Marylin Stowe, one of England's top divorce lawyers: Lady Graham Moon has gone down in English family law history for acting like a milkman, except that she was delivering to her neighbors the contents of her estranged husband's valuable wine cellar.

The act of revenge may feel good in the moment, but soon thereafter, people are reminded of how they felt to have evoked the desire for revenge to begin with.

The stakes become even higher when that cheating ex and you share children together. Indeed, the Journal of Experimental Social Psychology study found that feelings of revenge support endless cycles of retribution that may emerge in the context of conflicts between families. And we all know how that can turn out for parents and children alike.

So take a page out of the book of Cersei, the Queen of Family Dysfunction, and now, the Seven Kingdoms. She should have listed to Mark Twain who said: "Therein lies the defect of revenge: it's all in the anticipation; the thing itself is a pain, not a pleasure; at least the pain is the biggest end of it."
