Revenge
The action of inflicting hurt or harm on someone for an injury or wrong suffered at their hands
Before you embark on a journey of revenge dig two graves
I will hurt you for this. I don't know how yet but give it time. A day will come when you think yourself safe and happy, and suddenly your joy will turn to ashes in your mouth and you'll know the debt is paid.
Any harm you do to a man should be done in such a way that you need not to fear his revenge.
