The ultimate irony here...
"Our table doesn't want to think about morality when we play... we just want to kill stuff and take their loot."
In any other group except gamers... if they were told the baseline premise of D&D, the PCs would be considered the evil ones. The only reason to need an "always evil" race is to find a way to justify in the minds of the players that they are in fact not being evil MFers who go around killing anyone or anything that gets in their way in their quest to find gold.
But if you're going to sit here and say you want to be able to do just that... just "play" without having to worry about "morality"... then you should probably just accept the fact that all PCs in the baseline prototypical D&D are essentially evil themselves. You are playing a bad person in a society where you will usually not get arrested for murdering anyone or anything you come across out in the wilderness, and stripping corpses of their property after the fact is perfectly fine.
Once you accept who you are and who your PC is and what you want your PC to be able to do in this prototypical style of D&D without any true consequences (other than going to 0 HP and "dying")... you don't need an "Always Evil" servitor race in the game anymore. Because trying to reflect your evil with
another evil is unnecessary.
