You're adding a LOT of your own conjecture to "humanize her as much as possible." No matter what, the character deserves some sort of resolution. It never made sense to send her off to pasture like this, the story itself didn't fit together and they have still never really explained why this story even happened (as in, why did she even jump off ICC? Just fucking bizarre).
So for the fans of the lore and the integrity of the story, the character deserved to be brought back to the beginning - her origin, her motivations, and on. And it just so happens that large swathes of her story are things humans can relate to or even admire to some degree.
But feel bad? No. Over and over, important characters are seen giving measured responses that are true to the ideals that both factions stand for (honor, etc). There's also some who want extremely harsh revenge. And the only they can do that isn't corny af is to send her off to purgatory for a decent while if not forever.
