See, in FMAB impulsive fits the bill, perhaps immature (to a point) as well. But pettiness and vindictiveness? Hardly. ESPECIALLY the latter where he talks down somebody from their own vindiction... TWICE.
If there's anything vindictive about Edward it's his disposition towards his father, who, is a completely different person in FMAB (I've heard he's quite the womaniser in FMA.)
But, believe it or not. Most complaints I've heard against Edward Elric are nothing like what you've said.
See, with your criticism there is room for discussion.
With "he's short, loud and useless" pretty much leaves you in a hopeless place.
How the hell is anybody supposed to argue against that xD
