Troughtout the whole series, Kakashi doesn't really show that much in liking Naruto. He never really smiles at him or says anything that great about him, he just acknowledges his strength. Does he even like him? Well even from the begining, Naruto pulls a prank. And when Naruto performs the resangen, kakashi even says "how did this <u>brat</u> do this move" or something like that. I dont really know, it just seems to me that even Kakashi doesn't like Naruto.
