What Tosk said is common-sense.
You calling it narcissistic merely shows your own biases you project onto others.
As for Picard - the borg crushed Picard's "iron" will with little more than an afterthought and used his knowledge and skills to bitch-slap the federation.
Deal with it.
And, yes, that was partly Picard's fault, too. Capturing the enemy captain is quite a feat for the capturer - far harder than merely destroying the enemy ship; it highlights either the incompetence of the captured or his naivete.
It actually showed how much more powerful the Borg are than the Federation. Picard's orders were to investigate and keep the Borg busy while a fleet was being prepared to properly fight the Borg. Picard went in knowing it could well be a suicide mission or at best, a game of hide and seek, to keep the Borg occupied.
Yes, Picard knew from the start that the borg's military technology is far better than the federation's and that the borg massively outgun his ship.
He also knew that drones can easily teleport through federation shields and are, individually, more than a match for his men.
And he found out that the borg wanted him - personally.
Yet - there were no additional security personnel (or measures that fulfill the minimal standard of springing into action at his capture - we're not even talking about being effective) on the bridge or any other part of the ship; no other measures to prevent his capture (yes, up to and including suicide pills).
As said - Picard was either incompetent or ridiculously naive; most definitely culpable.
Interesting idea about suicide pills, but that does highlight an important aspect of TBOBW. The Borg should not have been allowed to get their hands on Picard, though I wonder if the Borg would have just picked someone else fairly high up the ladder? In any event, Picard's capture compromised the security of the entire Federation. I'm sure the Vulcans were significantly unimpressed by the lack of "the needs of the many outweigh the needs of the one" actions there.
