Good answer from LYN, but I would say that "meekness" is a better antonym for vengeance, but that is just me. Meekness means having the ability and power to act out, but choosing not to do so, because you want to forgive, or channel your feelings elsewhere. Whereas vengeance is acting out without concern in order to have revenge.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
