And the damage done to Tuvok by this choice. Worth it?
Tuvok volunteered for the mission. He also accepted a life in StarFleet which comes with numerous dangers, and knew something like this was possible.
By this analogy we should blame every other SF captain for ordering their crewmembers to do seemingly 'ridiculous missions'... even ones that could result in their deaths.
If I recall, this was something SF thought to be important if you wanted to be in the Command division of SF... ordering people to go into their deaths.
What's worse, Janeway wanted to go on this mission ALONE... Tuvok and Torres volunteered... no... INSISTED to accompany her.
Also, there was no seemingly permanent damage to Tuvok from his assimilation. He was in the Collective very briefly. Similar amount of time, or even less than Picard.
Yes, the Vulcan psyche is capable of being permanently damaged, but also due to his ability to control emotions, Tuvok would have been able to cope with his assimilation experience better than Picard.
Hardly. Starfleet still struggled in First Contact with all the Federation's resources,, while a loan ship continually defeats them..
You realize of course that VOY got stranded in the DQ well before FC movie and was still getting back home and as such, SF didn't have access to Borg corpses.
VOY crew did.
SF did manage to upgrade its technology however in the interim to severely damage the cube in FC... at the very least, they didn't suffer massive losses like at Wolf 359.
