Maybe the goal is to convince all people that they are things.
(Once that's done, the work of damnation has been achieved - and the rest is just Satan having fun.)
To do this by making the world one that treats all-of-reality as things - only things are really-real.
And to make all things inter-convertible (e.g. by money and bureaucracy).
Then to make all the inter-convertible things into 'equal' units.
Then to do whatever-is-fun with the things - including exploiting, tormenting or eliminating them...
Because - Hey! - it doesn't really matter, does it?
Because they admit they are just things; and things don't mind.
(How could they mind? They are just things, after all!).
And there's always plenty more (equal) things, where those came from.
