If there are going to be people out there making war on other people, don't you think it's a good idea for some of those people to at least follow a code of ethics? Not 'honor' but something you can pin down and be sure of, something with the same rules for everybody.
All through my life, I was hated on. When I was in middle school, they used to write in my rhyme book, 'You suck' or 'This sucks.'
