Grow up about the Mengele' shit, people. Drop it; get back to the question.
Is it evil, what she's doing? For a certain definition of evil, yes; for black-and-white, yes, absolutely. Everyone else is focussed on bits and bobs, though, and they're really
really not looking at the real issues that a) the SR world faces in this, b) the actions taken, c) the opponent (CFD) Butch is going up against, and d) the limitations imposed upon her.
Let's take C first.
First off, CFD is a disease that can
literally take one, two, or
more months to manifest. Calling it difficult to detect is a massive understatement; people who are in frank symptoms don't even necessarily know it. Secondly, acquiring CFD is
not generally a random occurence. It isn't airborne; it's blood- and fluid-borne, and though it could
possibly be contact-borne, victims or those taken over generally have to intentionally transfer it. This makes its rapid spread a matter of
guidance, of biowarfare. And it doesn't even kill a person, or make them sick in a 'standard' way; it 'only' changes their personality. Which means
finding someone who is under CFD assault is a very,
very difficult and chancy proposition; anyone who you might hear about are going to be a) in frank symptoms, and/or b) already mostly taken over. Which c) is gonna suck.
Second, case D. Butch is operating mostly alone, on a shoestring budget, needing to do other work
as well as this to keep up her cash flow,
and being hunted and needing to cut loose and burn her operation to the ground at a moment's notice. She isn't set up in a nice cushy operation where people send their CFD victims to her, and she can do things nice and by the book. Since locating victims is such a cast-iron, she needs
some way to study the thing from the moment of infection onwards, and this crap just doesn't
replicate in a slurry of blood and monkey kidneys, you know?
Next, situation A. What
does the Shadowrun world face? It isn't
exactly mass extinction; people will still be alive, they just won't be ... themselves any more. But this is a very insidious 'Rise of the Machines' that doesn't impose from the outside in,
a la Terminator, but from the inside out. This is a case of viral-mechancial Body Snatchers. We won't be dead, but we won't be
us any more. And because this is
essentially a war of sentients, in which anyone -
anyone at all - can be turned into a combatant, this is
at least as bad as the UB. Worse, because it's clear once they're converted what 90% of 'the bugs' are.
Finally, B: the actions that Butch took. She infected people - I'd have to do a re-read to figure out roughly how many, but I'm sure it wasn't less than 25, and might be more than 100 - with a condition/disease that she knew wouldn't kill their bodies, but knew
would destroy their personalities. Did she get their permission first? Here's the kicker on that -
we don't know. I don't believe she did, however, which means that yeah, she DID as good as kill each and every one of them, as deliberately and systematically as any serial killer. Is that evil? Yes, absolutely. Is it necessary? No, not
necessarily - but considering the other people researching this stuff
are restricted by things like ethics and legal ramifications, she's gotten three or six times as far as anyone else in figuring this thing out.
That's fine, Wyrm, but is she a monster?
Depends on how you define 'monster'.
- She has done monstrous things; she is a monster. She is the monster we need in order to find a vaccine/cure for what is being done to 'us'.
- She feels guilt for what she has done; she is not a monster. I would give Butch about an 85-90% chance of suicide once she's found/created and seen repeated successful applications of a cure. Because she is torn up about it. But she's a woman on a mission, and bad things will be done until she succeeds in that mission.
YMMV.
Addendum.
If you really
do want to compare the two - no, she isn't Mengele' reborn, just as bad as him, or whatever. She has a specific target, she doesn't enjoy the pain she inflicts, etc. etc. Has she done monstrous etc., see above.
