What does the symbol of the "left" hand or "glove" mean in literature...eg Margaret Atwood has used it in her novels?

It symbolizes deception or a reversal of true intent, or something sinister; traditionally in Europe, the left hand is viewed as the "sinister" hand, and some languages even use "sinistro" to mean the left.

There is an example of presentation of a left-hand glove to the Duke of Prussia by the city of Konigsberg; it was a symbol of submission to his rule.

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.
