No, his act is more like a feral instinct to satisfy his own hunger rather than enjoyment. He may count in other works, but this is Star Wars. There are already at least one villain who does the same thing as Nihilus but with straight moral agency - Vitiate, an omnicidal Sith with a serious God Complex (Something Nihilus completely lacks) who killed countless people from planets to planets, as well as butchering his own Sith subordinates, so that he can live eternally and rule the void of universe forever as its immortal emperor.

Not to mention Palpatine or Tarkin.
