Well, it really comes down to the fact that a "soul" is a magical concept. There's no science behind saying something has a soul if we're going to say it is more than just having the ability to think.

What we do know is that in the RWBY universe, everything but the Creatures of Grimm are at least said to have a "soul". Now, whether or not the monsters really do have a soul remains to be seen. I would say it is quite possible they have a dark equivalent of a soul.

Who knows? Maybe if the Creatures of Grimm had won, they'd be telling their young that "we are the darkness, they are the light".
