I don't think jiraya should die...maybe get heavily wounded and then someone come to the rescue...anyway the 4 hogake had been konohas yellow flash right so in terms of speed naruto doesn't even match up to him but in terms of raw power naruto is better due to his chakra level...so you see in some terms naruto is better than the fourth but in other terms the fourth is a lot better...what i mean is that every ninja has his own weakness and powers
