Repay no one evil for evil, but give thought to do what is honorable in the sight of all. (Romans 12:17 ESV)
Revenge is not the answer as if you want to do wrong to others it will just be a circle which is a cycle with no end. The strength it takes to do evil is not worth it. There comes a time when someone has to be the bigger person and let it go. Yes the hurt you feel will clog up your thinking process so be mindful and think how much you will loose if you go forth with your revengeful plan. Would someone innocent get hurt or would it back fire and lead to even more pain? Is it worth the chance?
