I am SO confused.
You WANT Janeway to help kill off abductees?
Did you watch flesh and blood or friendship one?
You give a backward self destructive people, a means to save themselves, but they see an alternative use for that lifeline which will increase their short term luxury at the expense of their long term well being usually divided right down the line between the 1 and the 99 percent.
The Prime Directive is about avoiding UNFORESEEN consequences.
If Janeway had imagined that the Hirogen would invent hypersentient Hologams to torture, murder and respawn, torture murder and respawn adinifum, would she have still forced that holomatrix on that Alpha who REALLY REALLY wasn't interested in the technology?
