Several mechanics and skills use blood and corpses to function, plus if you removed all bodies after a battle ends, you can't pick up their loot.
This.
Bodies can't be removed so easily because they can be potentially eaten or absorbed as source points (or maybe needed for later quests. I remember at least one occasion in DOS EE where you had to dig up some old bones and burn them).
Also, I would kindly asked everyone to keep calm and polite. Rude mode is not going to be good for anything.
