These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Draco in Leather Pants: Averted. Azula's past is not whitewashed, and she isn't Easily Forgiven (nor is she a particularly good person until quite late in the game - her reasons for doing the right thing in most of Heart and Path are almost entirely selfish, though she does make progress).
Word of God: One of the author's motivations for writing the series was to do an Azula redemption fic that didn't involve this trope, forcing her to actually earn her Heel-Face Turn. He likes to think he succeeded.
Magnificent Bastard —> Guile Hero: Azula. She shows she's still got it even before she's completely sane again. The creator did a mighty fine job remaking this aspect of her character as Azula manipulates others for her grand plans just like in the actual series.
