While I agree, I think he means that even if that particular doctor were to be removed by whichever means, her superiors would quickly just pick up a resume and find someone else to replace her with within the hour, who, for all we know, may turn out to be even worse somehow. With that perspective in mind, taking revenge only on her would serve no tangible purpose or have no benefit other than personal satisfaction (which I'm still all in for, btw) since she's just a tiny, invisible drop in an ocean full of bigoted douches.
On the other hand, Nia has the right idea but goes about it in the completely wrong way. I ended up shaking her hand near the end but I have to admit I hesitated for a moment. It felt like I was choosing the lesser of two evils to fight a greater evil. Some real DBZ shit right there.
Yeah, someone would replace her right away, they may be worse, but maybe not, hard to say. And depending on how it goes down, it could even make things worse, like making a supervillan kind of backstory situation. But that all depends on how much detail we want to go into it. I still say it is better to try.
It could be just a short scene, where we have a little talk with Nia/Sui, and the next day, we chat again with her telling us it's done.
I don't disagree with you, I did the same, but I figure the more power we gather, the better her methods can become. She does what she does out of desperation, so the more help he get her and the more of a network we build, I think we can make that all so much better. But you have to start somewhere, and she has rarely had people she could rely on before. The more we work with her, the less 'evil' her 'evil' will become.
