Pure Evil

Villains who are the most detestable and evil characters. They don't have any tragic or understandable motives for their acts. They usually commit their heinous acts for selfish or sadistic reasons. They are aware of their horrible acts and continue doing it because they enjoy it. They lack any sympathy, empathy and any human decency to speak of.

Note: Don't add pure evil or tragic together. As once again, pure evil characters don't have any tragic background to speak of. Either that or any tragedy they may have experienced doesn't justify their actions nor do they have anything to do with their tragedy.
