All things that live must die. Man alone it seems lives all his life in the knowledge of death. And yet there is more to life than merely waiting for death. For life to have meaning, there must be a purpose. A man must pass something on – otherwise he is useless. For most men, that purpose revolves around marriage and children who will carry on his seed. For others it is an ideal – a dream, if you like. Each of us here believes in a concept of honor: that it is a man’s duty to do that which is right and just; that might alone is not enough. We have all transgressed at some time. We have stolen, lied, cheated – even killed – for our own ends. But ultimately we return to our beliefs. We judge ourselves more harshly than others can judge us. We know that death is preferable to betrayal of that which we hold dear.
