True, though I didn't mean evil that literally. But it's interesting, I don't get the sense that the government would have subjected her to the sort of white room treatment you describe. This isn't the British fascist regime from V for Vendetta, and most of what we know about the government and what they would do to her is told from the unbiased perspective of terrorists who have their own agenda.
When all characters and factions are portrayed as grey, it just seems out of place to have another organisation, which is talked about in almost mythical tones, be genuinely white. We know very little about them, and what we see turns out to be a manky old boat. I don't get that 'and everyone lived happily ever after' vibe from the end.
There was a great Outer Limits episode where a woman gives birth to a child in a sterile world, I think she was also black as well, and whilst she was treated fine at first, slowly the gloves came off as people started to be people.
