Re: Anyone else think they should have left the Borg well enough alone
That's what makes the Queen boring. The whole 'need a mouthpiece' thing worked once with Locutus, but what do the Borg need to negotiate for?
And besides...if there was a Queen all along, why did they need Locutus anyway?
I doubt that the Borg wanted Picard as a "mouthpiece" at all.
Think about events from the Borg's point of view.
The see the Enterprise at J-25, learn it is the most powerful ship in the Federation. Picard is the captain, so obviously someone of great importance. As far as the Borg are concerned, Picard is the poster boy for the federation.
Then, apparently the enterprise has technology more advanced than the Borg! it just disappears, hurtling back towards federation space! of course, that's Q's doing, but the Borg don't know that.
The Borg Queen is as paradon said. The Collective is one single organism (Picard even says so in I Borg, and he would know), and the Queen is like the conscious mind. Think of the drones as being like brain cells, and the Queen is the mind formed by all the brain cells working together.
Now, the Borg Queen has the power to get what she wants, when she wants it, and no one is going to stop her. In short, she is a spoiled brat.
So she hops a Cube to the Federation, and decides to go after Starfleet's poster boy. After all, Picard represents the Federation. he's the captain of the frigging FLAGSHIP! get him, and it's certainly going to send the rest of the Federation a message.
So assimilate him. Not as a mouthpiece, or a voice to speak for the Borg. I mean really, what do the Borg have to say that is better coming from locutus? Not much.
But assimilating Picard is a rape. And rape is about power. Assimilating Picard, therefore, wasn't about the Borg getting a mouthpiece. it was about them saying, "This is what we can do. We are more powerful than you. You are now my bitch."
And don't forget what Picard said in First Contact. That the queen wanted him to give himself freely. As Garak said, the greatest victory you can win is one where you make your enemy realise that he was wrong. That's exactly what the Borg were trying to do to Picard.
And that's why they assimilated Picard.
