Can't totally agree with this. While reciprocity is certainly a noble goal, I see more value in forgiveness that comes unconditionally. I can hope that my gesture results in a positive influence on the other guy, but the true reconciliation is with myself. Your mileage may vary.
While you are forgiving unconditionally, just make sure you keep one eye your enemies intentions.
True it is in within oneself, but just in case, a good application of violence despite what your mama told you, will solve problems
There will be no "value" when you are dead. Unless you are in category of Christ or Obi Won Kenobi
