Revenge is about the other person; intervention is about the thing you are protecting.

Revenge wants them to suffer; intervention simply wants the harm to stop.

If I had been acting out of revenge, I would have confronted Mark the moment I found the lace, would have screamed, would have made sure he felt the full weight of my pain — and in doing so I would have warned him, given him time to move the money, hide the evidence, lawyer up, and turn my anger into proof that I was the unstable one.

Revenge feels powerful and is almost always self-defeating, because it prioritizes the satisfaction of the moment over the outcome that actually matters.
