Ok now that I have your attention the subject is what person you think is the biggest idiot of any anime and why. Here is a example:

Naruto from the show naruto!
Why: He loves a girl who does not love him can not realize hinata loves him and then when the one guy standing in his way of being with the one he really loves leaves he risk his life more then once to bring the guy back. He also runs into a major fight while making a big scene and after the scene calms down all he achieved in doing is letting the enemies know he was there.
