No, the poet is persuaded that the guy he killed was his true adversary. He feels that the other man was chosen by fate to be his adversary. Fate has brought them together at a time when both of them need each other's help, so they join forces and fight against all odds. The poet kills his rival but does not rejoice over it; instead, he feels sorry for him. This shows that even though you may hate your enemy, you cannot kill him. You can only hope that heaven will do it for you. The moral of this story is that hatred never brings happiness it only brings more hatred. So next time you are about to fight with your enemy, try not to hate him/her because eventually you will be killing yourself. Also, don't take things too seriously. Have fun with life because soon enough it will be over anyway.
