Revenge...

He came. He killed. He cut it into pieces, and put them for sale. People came, chose and bought whatever amount they want. They ate not with a pinch of remorse but with delight. This all happens with our sound knowledge and we are fine with it. Understandable. Then, why all the uproar about people like Saddam Hussein? Is it because they are not completing the process after killing? Or is it the sympathy for the like or is it the revenge against the killer? What happens if animals decide to take their revenge against us?
