[The Thing] is the Thing evil or is it just a creature acting on instinct? Was it tying to leave earth or go somewhere else on earth?

Yes, I'm piggybacking off the Thing post from yesterday. 

Also, was the Thing the pilot of the spaceship at the beginning of the movie or perhaps a prisoner/wmd?

I believe in one version it was supposed to have been a creature that was inadvertently collected by the aliens that made the spaceship.  It assimilated the other specimens and crew, causing the ship to crash land on Earth thousands of years ago.

It's not evil, it just has a method of acquiring food and reproducing not widely seen in macro-biota on this planet.
