[Demons are complex creatures, one that can't be quantified or categorized using normal means. They could be nothing more than animals, mindless, senseless, brutal, and bloodthirsty. They could be intelligent beings, smart, sinister, conniving, loving, hateful, shrewd, down right evil. But they could also be viruses, poisons, thoughts, urges, sins.
This more than proved that humanity is not really the most versatile race in all of the cosmos, but rather the demons. They can exists in any shape or form, live for thousands of years with a life that's practically immortal, without the need for them to do anything other than live, eat, sleep, breathe and fuck! If a demon dies it could be attributed to nothing more than their incredibly violent and vile nature, they thrive on chaos, on anger and on pain, and very much on hate, greed and pride.
