This story consists of the ongoing struggle within every human; how the negative and positive thoughts combat each other. Every person, in his life, faces and experiences the moments of pain, helplessness and failure. When the person transforms his deprivations and pains into his negative thoughts, he ruins himself and makes the life of other people also difficult.
In this story when the bat resolves to avenge cruelties of others, spoils the lives of hundreds of thousands. How our internal negatives feelings and beliefs, in the garb of appealing arguments and sympathies put us on the track of revenge. How we ruin others' peace of mind just for the satisfaction of our own ego.
This is the real essence of this story; how the negative twist of mind traps a person and makes him an extremist. Who wins and who loses this battle between negative and constructive thoughts; you will know after reading this short story. Many times what we call our victory, in fact is fulfillment of our selfishness and satisfaction of our false ego wrapped in false pride
