What's one word that describes a villain who will do anything like deceit people, abuse his powers and murder to get what he wants (Please DON'T SUGGEST the word MACHIAVELLIAN!!!!!!!!...)

I checked a dictionary and found unscrupulous and unprincipled. Other words might be evil, wicked, infamous, flagrant, flagitious, atrocious, villainous, nefarious.
and I don't want a term that refers someone as immoral or purely evil too...
Mephistophelean
