Why do movies and TV shows with revenge scenes sell? It's because we wish we could do it, too. Think about the last time someone hurt you - your first thought was probably, "I'll get him/her for that". If this sounds like you, don't worry. You're not crazy.
"Wanting to seek revenge is a really normal, innate reaction," explains psychologist Dr Mary Casey.
"Whenever someone does something to betray you, it's usually unexpected and often leaves you feeling like a fool. You feel powerless. Taking revenge simply makes us feel more powerful in a situation where all the power has been taken from us."
