Yeah, but he grew and came out of it, becoming much friendlier, such as when he helped Sokka out to bust out his and Katara's dad from the Boiling Rock, and helping Katara with her closure. Zuko could still be a kitten, yes, but he grew nicely in his redemption. I wish Sasuke had had that much love put into his redemption. I know for my fic, I'll make sure it is that good, or I'll die trying.
i agree, but the road to his redemption was just exhausting to me. it was like 1 step forward and two steps back. i commend uncle iroh for being so patient with him, because i would have quit long ago on zuko.
