"It's the Thing!" Charles Wallace cried. "It's the Dark Thing we saw from the mountain peak on Uriel when we were riding on Mrs. Whatsit's back!"
In a way this harkens over to the fate vs. free will debate happening next door to good vs. evil – if people do bad things because there's a black cloud over their planet, are they really responsible? What role does choice play in how the Black Thing influences a society?

"But what is it?" Calvin demanded. "We know that it's evil, but what is it?"
Mrs. Which's answer is circular: it's evil 'cause, well, you know, it's evil.

Suddenly there was a great burst of light through the Darkness. The light spread out and where it touched the Darkness the Darkness disappeared. The light spread until the patch of Dark Thing had vanished, and there was only a gentle shining, and through the shining came the stars, clear and pure. Then, slowly, the shining dwindled until it, too, was gone, and there was nothing but stars and starlight. No shadows. No fear. Only the stars and the clear darkness of space, quite different from the fearful darkness of the Thing. (6.4)
It's interesting that the defeat of the Black Thing doesn't lead to the universe being lit up like a baseball stadium, but rather to an absence of unnatural darkness. It's almost like the battle isn't so much between evil and good as between evil and the normal or the natural.
