If that's the case then consider this; how would you say they reproduce? They certainly don't look all that natural (unless that's what the RWBYverse CALLS natural). Now that I think about it, they kinda remind me of the Heartless in design.

Oh God...

what if they... suck out human souls for nourishment and then use the empty carcass to turn into another Grim?

...Where do I get these ideas? They eat dust and regurgitate it into baby Grims. Unless they're egg-laying Grims, in which case they eat both people and dust, digest the bones and flesh, reshape it all, and lay eggs somewhere secret so the baby Grims can hatch in relative safety.
