Sorry about this rather extensive look at Asami, but haters be hatin, and the girl got me thinkin’.
This idea going around that Asami and her Father staged their entire fight so that Asami would get an IN with the Avatar makes no sense.
First of all Korra was already hanging out with Asami, even going over to Asami’s house. They went racing together. They were already becoming friends. Korra had no second thoughts about Asami. So Sacrificing Amon’s main weapons producer and crippling their ability to make weapons is not worth Korra and Asami being CLOSER.
Secondly, Amon has no NEED for a secret agent in Korra’s life. He’s saving Korra for last anyway. This plot makes no sense with the tone or flow of that entire scene and suggests that Hiroshi purposefully led everyone into his secret liar, revealed his big plan to them, and then on purpose, with prior planning, got the s**t kicked out of him by his daughter and his company destroyed. For what? For Asami and Korra to have sleepovers?

Now, on a narrative or tone-wise note: Having Asami secretly be evil is not Bryke’s style, and would actually be contrary to their over all narrative flow.
One thing that Mike and Bryan do so beautifully is subvert over-used cliches, especially when it comes to their female characters.
Toph was a bossy rich girl as well, remember? Ty Lee was girly and liked boys. And yet ultimately neither of them fell into the neat little cliche boxes that those overly simplistic descriptions sorted them into.
I feel like Asami is very much the same way. We are so trained by media to be untrusting of any woman who wears lipstick and has money. Again and again we see these women, Femme Fatales, attractive, too good to be true, and we are taught that they are secretly money grabbers, secretly manipulative, secretly EVIL. It’s a tired, old, problematic, sexist cliche, and Asami does not play into it. She is genuinely kind, and sweet, and generous. Gorgeous without being bitchy, friendly without being manipulative.
She continues to subvert our expectations of what she is supposed to be: the helpless rich girl, the “other woman”, the untrustworthy. But she’s not those things. She isn’t helpless. In fact she saved everyone. She isn’t some competition for Korra to overcome, because the girls have not seen themselves as rivals. And she isn’t untrustworthy. At all. In fact she’s been kinder, and more trustworthy than MAKO has been up to this point.
Asami is important to the overall tone and flow of the story, not only because her driving and martial arts training will be useful to the plot, but also because of her role as a non-bender and foil to Korra’s personality. Like Katara and Toph’s dynamic, Korra and Asami are foils, and their interactions serve as a good comparison and driving dynamic for the group.
Her relationship with Mako is a wonderful example of benders and non-benders living together peacefully: A non-bending bending fan who’s mother was killed by fire bender, and is DATING A FIREBENDING BOY because she judges people by their actions, not their abilities.
Making her EVIL would be a cheap narrative shot that would fly in the face of this really interesting and unique dynamic that has been set up. And people that think Asami is STILL evil, honestly, just sort of look like they WANT a reason to hate on the poor girl because she subverts a stereotype they want to hate, and “gets in the way” of Makorra.
