‘Forgiveness’ is the most natural of human instincts… or so was said in the film Revenge ‘.

This phrase made me think of the ‘survival’ bandwagon that we each so easily jump on.
Why should we forgive, when in survival terms it means forgetting the reasons we were first in rejection of that which guided us away from harm?
I’m intrigued by this thought, so ‘answers on a postcard’ please !
