[Cube]. What was the final purpose of the Cube?

I know the explanation probably trickled in on one of the direct-to-video documentaries about the Cube.  I'm not going to waste my time watching those.  Did they ever explain what the cube is for, why they would spend so much freaking money on this thing just to torture a handful of people?

There was no purpose, and indeed no one person was in control. The Cube was created almost by a type of collective madness by the Military Industral Complex. 

That was what was so scary about it.

What kind of service could it have served? 

None. Absolutely none.
