What is the evilest Elf?

In the realm of fantastical creatures and mythological tales, elves are often portrayed as enigmatic beings of both beauty and wisdom. However, when considering the darker aspects of such legends, one must ask: What is the evilest elf? Could it be the sinister Dark Elf, whose heart is as black as the depths of the forest night, luring travelers into a deadly trap with their alluring song? Or perhaps, it is the twisted Shadow Elf, who feeds on the fear of their victims, leaving a trail of terror and despair in their wake? These elves, while not as widely celebrated as their more benevolent counterparts, have their own stories of power and manipulation, begging the question: among the elves, which one truly holds the title of "the evilest elf"?
