I found the transcript to Avatar episodes. There is two scenes I find interesting. Seriously, Zuko has come a long way before becoming Firelord. Kudos to this website:

Zuko: First of all, in Ba Sing Se, it was Azula who took down the Avatar, not me.
Fire Lord Ozai: Why would she lie to me about that
Zuko: Because the Avatar is not dead. He survived.
Fire Lord Ozai: (alarmed) What!
Zuko: In fact, he probably is leading this invasion. He could be on us right now.
Fire Lord Ozai: (stands up and points, furious) Get out! Get out of my sight right now if you know what’s good for you.
Zuko: That’s another thing. I’m not taking orders from you anymore.
Fire Lord Ozai: (seething with rage) You will obey me or this defiant breathe will be your last! (Ozai begins to walk towards Zuko, until Zuko unsheathes his broadswords and brandishes them at him.)
Zuko: Think again! I am going to speak my mind and you are going to listen.
Zuko: For so long, all I wanted was you to love me, to accept me. I thought it was my honor that I wanted but really, I was just trying to please you. You, my father, who banished me just for talking out of turn. (points a sword at Ozai) My father, who challenged me; a 13-year-old boy to an Agni Kai. How can you possibly justify a duel with a child
Fire Lord Ozai: It was to teach you respect.
Zuko: It was cruel! And it was wrong.
Fire Lord Ozai: Then you have learned nothing.
Zuko: No, I’ve learnt everything! And I had to learn it on my own. Growing up, we were taught that the Fire Nation was the greatest civilization in history and somehow, the war was our way of sharing our greatness with the rest of the world. What an amazing lie that was. The people of the world are terrified by the Fire Nation! They don’t see our greatness, they hate us! And we deserve it. We’ve created an era of fear in the world. And if we don’t want the world to destroy itself, we need to replace it with an era of peace and kindness.
Fire Lord Ozai: (laughs mocking) Your Uncle has gotten to you, hasn’t he
Zuko: (closes his eyes for a second) Yes. He has.
Another episode:
Zuko: I like it when you express yourself. (he reaches for her, but she backs away)
Mai: (yelling) Don't touch me. I'm still mad at you.
Zuko: My life hasn't been that easy, either, Mai. (Mai interrupts him)
Mai: Whatever- that doesn't excuse the way you've been acting.
Ty Lee: Calm down, you guys. (cut to Ty Lee and Azula sitting behind her) This much negative energy is bad for your skin. You’ll totally break out.
Zuko: (angrily) Bad skin (Ty Lee cringes. Cut to shot of Zuko looking toward her) Normal teenagers worry about bad skin. I don't have that luxury. My father decided to teach me a permanent lesson on my face. (Zuko points toward his scar) (Cut to shot of Azula, Zuko and Ty Lee)
Ty Lee: Sorry, Zuko, I... (Zuko walks away from them and the camera follows him)
Zuko: For so long, I thought that if my dad accepted me, I'd be happy. I'm back home, now my dad talks to me. Huh, he even thinks I'm a hero. (cut to Azula, who smiles at these words) Everything should be perfect, right (cut to over-head wide shot of the four teens sitting around the fire) I should be happy now, but I'm not. I'm angrier than ever and I don't know why.
Azula: There's a simple question you need to answer then. (she leans forward) Who are you angry at
Zuko: No one, (he looks down) I'm just angry.
Mai: Yeah, who are you angry at, Zuko
Zuko: Everyone... (he covers his ears in frustration) I don't know.
Azula: Is it Dad Zuko: No, no!
Ty Lee: Your uncle
Azula: Me (Cut back to shot of Zuko who shakes his head in frustration)
Zuko: No, no... No, no.
Mai: Then who Who are you angry at (The camera quickly pans right, stopping on Azula) Azula: (sternly) Answer the question, Zuko.
Ty lee: (pleading) Talk to us. (Cut to shot of Zuko looking confused and frightened)
Mai: Come on, answer the question.
Azula: Come on, answer it. (Cut to wide shot of group. For a moment there is silence)
Zuko: (yells suddenly) I'm angry at myself! (Zuko throws his arms down and the campfire bursts into a column of flame. The girls cover their eyes to protect themselves from the fire. Cut to a close shot of Zuko as wind and embers fly through his blowing hair. The fire burns out and the scene grows dark. Cut to a wide shot of the group)
Azula: Why (Cut to shot of Zuko looking out at the sea with Azula sitting behind him)
Zuko: Because I'm confused. Because I'm not sure I know the difference between right and wrong anymore.
Azula: You're pathetic.
Avatar is a thought provoking cartoon. I meant that in a good way though.
Have faith in me.
But then again, those who do, always end up disappointed.
Signing off now.
