In my opinion the reason for his hate of Naruto lies not just in the fact he's only witnessed him making stupid decisions, but the fact that he regards his father as a failure because of the 9 Tails situation, and that Naruto is the embodiment of that hatred, he's the son of the man who was his ultimate Rival, and who he relied on to save the ninja world, Naruto hasn't done that yet..., and the nine tails fox his failure now is within Naruto, so in his opinion he's the embodiment of the "FAILURE" of the man he respected over anyone.
