I don't see how killing can be the best revenge. Killing is final, you have one opportunity and it is done quickly. Wouldn't it be better to seek revenge in other ways besides mass murder, thus knowing that person is going to miserable for sometime and you're the cause of it. I guess that is the difference between those who really understand revenge and those who don't.
Wrong. Human beings are savage, beastial, creatures at worst. So we have a choice to aspire to be something greater than this or remain in the muck with the lowest comon denominator. What contimues to shock me is the sheer amount of people who actively chose to remain the lowest common denominator.
