I wonder if folks realize the irony of Omega:
The Section 31 novel Cloak
establishes why the Omega Directive came to be--it was due to an expirimentation on the molecule by a group of ambitious scientists supposedly subsidized by Section 31.
This book, and the other books in the miniseries, go to great lengths to demonize The Bureau as either incompetent or just plain evil. Our heroes dismiss the arguments of the 31 agents out of hand, swearing to bring them down, someday.
And yet...Janeway is forced to effectively employ Section 31's methods to do what is neccesary to save lives...the justification Section 31 asserts, as well.
