Re: Species 8472: What were their motives?
According to script, the Borg failed to assimilate any 8472. Therefore, they did no harm to 8472.
Non sequitur. Like Guy said, it's possible (and quite likely) that the Borg killed lots of 8472 babies. And mommies and daddies.
Except they have five genders. So would that be mommies and mommies and daddies and daddies and mommies?
I don't want to think about it.
