Revenge is never what you think it's going to be. There's no pleasure and glory, and when it's done your grief remains. Once a man does the things you're talking about, he will never be the same, and he can never go back to who he was before. Worst of all, no matter how many enemies you kill, you are never satisfied. There is always one more who deserves it. When it becomes too easy to kill, it never ends.
