While Janeway could be a hypocrite and moral moron in her decision making, earning her a reputation of being a fruitcake in Trek fandom, but was she right in donating the nano-bomb technology to the Borg to stave off the invasion of Species 8472? The Borg were evil and during the course of the "Scorpion" two parter, deceptive, but Species 8472 couldn't be second guessed either and their designs on the wider Milky Way after annihilating the Borg were most likely not going to be benign.
