IMO I often find Sfdebris' reviews/opinions very short sighted.
He doesn't understand metaphor's at all.
The Queen saw Unimatrix Zero as a cancer within the "body" of the Borg.
You don't make cancer beg, you cut it out to stop it from spreading.
Making the Drones beg would ruin the meaning of the metaphor
Blowing up the Cubes was her cutting out the disease.
It still holds true to the metaphor Dr. Crusher used to describe the Collective.
