Betrayal is perhaps the worst kind of human humiliation. Trust is given, words exchanged of steadfast support and suddenly for unfathomable reasons of family, loyalty, love or greater gain elsewhere you are cast aside. It's difficult to justify and painful to receive. It can bruise lives and is often the cause of a need, a want, a desire for revenge. And by some measure this is not like-for-like or tit-for-tat, this is exacted for at a much higher cost. They say Revenge is a dish best served cold. Our classic authors who range from Edgar Allan Poe and Alexander Pushkin to Susan Glaspell and Paul Laurence Dunbar serve it up in many a manner, in many a style but always with relish.
