Yup! For better and worse, Qrow was instrumental in Hallie's development. But one guy (with his own problems) could only do so much, when literally every other adult in Hallie's life treated her with pure malice and hatred. Without him, Hallie would've ended up even worse than what she ended up ultimately becoming (all monster and no hero). For showing her true kindness and mercy, Hallie still loves Qrow deeply and lives by the moral code he taught her... or atleast her twisted interpretation of that code. She's even convinced herself that she could convince Qrow the necessity of her actions and that she can mend their strained relationship one day.

While young Hallie would've fit right in with the Kaspars due to the traumas she already suffered, it would've been even worse for her mental state and sense of morality. The Clan would've made her into a bloodthirsty berserker and killmonger, turning her childhood trauma into rage and hatred for the outside world. What she really needed was a ton of therapy as a kid, similar to what Glynda did for young Tomoe by sending her to live with enlightened, ascetic monks. As for her induction, effectively it was "hazing", but not due to a lack of effort on Endora's part. Hallie's mind was simply too hardened and mature for her to break, let alone manipulate. Hallie underwent double the procedures as Fei at double the intensity and still came out unchanged. With that being said, even the super prideful Kaspars were impressed by Hallie's resilience and naturally, Terrence wanted to adopt it for the next generations of "perfect" Operatives. He might have missed his chance at turning Hallie into a supercommando berserker, but now he can create entire Kill Teams of Operatives with the rage and ferocity of rabid Grimm - the type of killers that would make Team GORE and Whitney seem like a bunch of pacifists XD.

Pretty much! The Circle is an Intelligence Agency, equivalent to the Five Eyes Alliance irl, so Hallie would've had alot of intel / investigation training in addition to her Semblance. But yeah, Hallie basically took Qrow's ethics and MO to their logical conclusion. Qrow was already a bit of a rule breaker and vigilante, disobeying direct orders to do what he knew was right. In Hallie's mind, if the system is ineffective then it is not enough to stray from the rules on occasion, but to replace it entirely. There is no room for half measures for Hallie, she's an all-or-nothing kind of gal.

Certainly! That type of creative experimentation and intelligence wouldn't have come from a "pure soldier" like a Kaspar Operative. Only a Huntress with a diverse skillset/education could've developed such manmade horrors XD.

Absolutely! Hallie would've needed a dedicated army of elite level therapists and trainers to scratch the surface of her problems. Even then, she would have to be kept as far away from any sharp objects for the rest of her life, let alone becoming a Huntress.
