[Justice League Dark: Apokolips War] Why did Darkseid feel the need to do this?

Darkseid beats the Justice League and kills a lot of the heroes. For those that survived he dismembered their bodies and transformed them into cyborg organism made to serve him as an enforcer. For example, wonder woman entire lower body, forearms, part of her face and upper torso were all taken out and replace with machine parts.

Now, darkseid did not have to do this. He was perfectly able to brainwash batman into being his servant and kept him 100% organic, so why then would he transform these heroes? Logically, they would move better and more accustom in their original body that the cybernetic monstrosity he turned them into. Also, wonder woman durability i wager in her old body was probably better than her new body (assuming its made out of the same material used by parademons for their armor).

As banal of an answer is it sounds, Dude just likes making cybernetic monstrosities.

He's a sadist, he's pretty unambigiously won, every major threat is crushed and he still has a massive army if something goes wrong. Why *not* make heroes into cybernetic monstrosities?
