Ok, The Fourth Intended To Seal The Kyuubi Inside Naruto To Create The Next Generation Hokage, Which Would Be Even More Powerful Than The Fourth. And, Assuming The Fourth Was Able To Fight The Kyuubi On An Almost Equal Level, He Expected Naruto To Learn To Become Strong Enough To Master The Kyuubi And Harness Its Power.
Another Thing To Think About Is That It Said That Naruto Was A Baby That Just Had Its Umbilical Cord Cut Off, Now Some Of You Say, "His Parents Died Fighting The Kyuubi", Well Not The Mother Seing As She Just Had A Baby! However, The Father Might Have Died Fighting The Kyuubi, And Might Well Have (I Know Lots Of People Say This) Been The 4th. But The Mother Must Have Died Giving Birth To Naruto.
